Best Wig Wag Lights For Trucks: Compare Relays and Light Kits

#1 · Best Overall

1. Stop-Alert WigWag 36

• Wattage: 120 W
• Voltage: 12 V DC

Best for: Programmable headlight flasher.

Why it ranks #1: Its listed compatibility includes headlights, LEDs, and other lamps, with 36 selectable patterns and a sealed aluminum enclosure described as waterproof.

Thirty-six selectable patterns and compatibility with headlights distinguish the Stop-Alert WigWag 36 from auxiliary-light-only relays. Its 12V–24V operating range and two 10A outputs support a range of listed lamp applications, while the integrated LEDs and program switch provide direct pattern setup.

The program switch lets installers choose among 36 flash patterns, providing more signaling options than a fixed-pattern relay. Two outputs rated at 10A each give buyers a defined channel limit, and the 12–24V range supports different vehicle electrical systems. Compatibility includes headlights, LEDs, and other lamps, making this model relevant when the goal is headlight wig-wag operation. Its sealed aluminum enclosure is described as waterproof, a useful property for a vehicle-mounted relay.

Skip it if you only need an auxiliary-light relay at 36W per channel; the Stop-Alert FW-X236 specifies that channel rating.

Truck owners seeking programmable headlight or other-lamp alternating signals can consider this 12–24V relay. Keep the 10A-per-channel limit in view when matching it to the lamps and electrical load.

#2 · High-Capacity Relay

2. Stop-Alert WigWagger 240

• Wattage: 72 W
• Voltage: 24 V
• Weight: 18.14 g

Best for: Automatic alternating flasher.

Why it ranks #2: This alternating relay is listed for 12–24V systems and LED or incandescent lamps, with 36W per channel stated in its key features.

A stated 150 flashes per minute gives the Stop-Alert WigWagger 240 a defined fast alternating signal for compatible vehicle lamps. It supports 12–24V systems, works with LED and incandescent lamps, and uses an automatic operating mode, making it a straightforward relay option for wig-wag warning patterns.

The 12–24V range broadens its potential fit across vehicle electrical systems, while compatibility with LED and incandescent lamps gives buyers flexibility in lamp type. Alternating patterns and the stated 150 flashes per minute provide the warning behavior; automatic operation means no manual mode selection is specified for normal use. The waterproof design addresses moisture exposure, and the included instruction kit supports installation. This is a flasher module, so buyers still need compatible lamps and suitable wiring.

Skip it if you need 36 selectable patterns; the Stop-Alert WigWag 36 lists a program switch and 36 modes.

This relay suits truck owners wanting automatic, fast alternating signals with LED or incandescent lamps on a 12–24V system. Choose it when those lamp types and the stated flash rate fit the installation.

#3 · Best Included Kit

3. Nilight 4PCS Strobe Lights

• Voltage: 12 V

Best for: Four-light synchronized setup.

Why it ranks #3: The four-light kit is explicitly compatible with trucks and includes a controller, 12 flash patterns, synchronization, and a 12-volt specification.

Four double-row, 24-LED strobe lights give the Nilight kit broad placement options for a truck, while its controller provides 12 flash patterns. The lights are described as visible in daylight and adverse weather, and the kit supports either hard wiring or a cigarette-lighter plug for different installation workflows.

The four separate lights let a buyer distribute warning points around a vehicle, and synchronization support helps coordinate their output. A controller offers 12 patterns through dedicated power and mode buttons, making changes straightforward from the cab. The choice of hard wiring or a cigarette-lighter plug accommodates a more permanent or less involved connection. Waterproof construction supports use in exposed conditions, while the stated 12V voltage sets the system requirement for this kit.

Skip it if you need 12–24V compatibility; the DIBMS PEC00259x8-DS listing specifies compatibility with 12–24V vehicles.

Truck and RV owners wanting four coordinated warning lights can choose this kit for its pattern controller and two connection options. Its stated 12V rating is the key electrical boundary to check against the vehicle setup.

#4

4. Stop-Alert WigWagger 72

• Wattage: 36 W
• Voltage: 24 V

Best for: 12–24V relay upgrade.

Why it ranks #4: A waterproof alternating relay for 12–24V systems, it provides a stated 36W per channel and is described as compatible with auxiliary daytime running lights.

A 36-watt-per-channel circuit gives this Stop-Alert relay more stated load capacity than a low-output flasher, enabling alternating wig-wag patterns for compatible vehicle lights. Its 12–24V range accommodates multiple vehicle electrical systems, while the waterproof design suits warning-light installations exposed to the elements.

The 72W total load rating, split across two 36W channels, gives buyers a defined capacity for auxiliary lighting rather than an unspecified relay output. Its 12–24V compatibility broadens the potential vehicle fit, and alternating flash patterns provide the wig-wag effect. The listed waterproof design is relevant for an exterior or exposed installation. This is a controller, not a complete light set, so buyers need compatible lights and an installation plan of their own.

Skip it if you need a complete lighting kit; the BooYu Y012 includes a dash strobe light and installation accessories.

For truck owners adding a relay to compatible auxiliary lights, this offers a stated 36W per channel and 12–24V operation. It is the better fit when you already have lamps and can handle the relay installation.

#5

5. Stop-Alert X2 Wig Wagger

• Wattage: 72 W
• Voltage: 24 V
• Weight: 14.2 g

Best for: Auxiliary lamp flasher.

Why it ranks #5: This 12–24V alternating flasher lists 36W per channel, but its disclaimer says it is not for headlights, limiting its truck-lamp applications.

A 36-watt-per-channel output and 12–24V operation make the Stop-Alert X2 a relay option for alternating auxiliary lights across more than one vehicle voltage. Its waterproof design supports exposed installations, but the manufacturer explicitly excludes headlamps, so its strongest fit is compatible LED or incandescent lamps elsewhere on the vehicle.

The X2’s two 36W channels provide a 72W total rating, giving buyers a concrete load limit for compatible lighting. Its 12–24V operating range can suit different vehicle electrical systems, while automatic operation supplies alternating wig-wag flashing. The waterproof design is useful where the relay installation may face moisture. The headlamp exclusion is central to choosing it: this controller is for LED or incandescent lamps other than headlamps, not a headlight flasher.

Skip it if you need headlight control; the Stop-Alert WigWag 36 is listed for headlights, LEDs, and other lamps.

Truck owners wiring compatible auxiliary LED or incandescent lamps can use this relay for alternating patterns on 12–24V systems. Its clear boundary is headlamps: choose a headlight-capable flasher instead for that job.

#6 · Weatherproof Mounts

6. DIBMS Surface Mount Strobes

• Wattage: 3 W
• Voltage: 12 V

Best for: Weather-exposed surface lights.

Why it ranks #6: The eight-light surface-mount set is listed for trucks and 12–24V vehicles, with an IP67 waterproof claim and 16 flash patterns.

An IP67 waterproof rating makes the DIBMS eight-light surface-mount set a practical candidate for trucks working in wet or dusty conditions. Its lights use six LED chips apiece and offer 16 flash patterns, combining a weather-focused enclosure with configurable warning signals for vehicle installation.

Eight surface-mount lights provide multiple placement points around a truck, while the stated 12V supply defines the system requirement. Each light uses six LED chips and the listing reports daytime visibility, which supports warning use beyond darkness. The IP67 rating and stated resistance to dust, splashes, shock, and corrosion address exposure during outdoor work. Sixteen flash patterns add choice in signaling. The supplied facts do not specify a controller or installation accessories, so plan accordingly.

Skip it if you need a listed controller in the package; the Nilight TL-201 includes a controller with its four lights.

This set suits truck and off-road owners who want eight surface-mounted warning lights with an IP67 rating. Its listed 12V supply and unspecified controller details make electrical planning important before installation.

#7

7. Xprite Hideaway Strobes

• Wattage: 6 W
• Voltage: 12 V

Best for: Drilled hideaway installation.

Why it ranks #7: Six white hideaway lights offer 20 patterns and a 12V universal utility-vehicle fit, but installation requires one-inch holes.

Six white hideaway strobe lights give the Xprite kit a concealed placement approach for trucks, pickups, and other utility vehicles. The 20-pattern control panel includes quick-select directional patterns, enabling operators to change signals without treating each flash mode as a separate installation decision.

The kit’s six light heads can serve locations such as headlights, taillights, fog lights, or interior mounting points, giving installers flexibility within its hideaway format. The 12V specification supports utility vehicles on that system, and the control panel manages 20 patterns with quick-select directional options. Buyers should account for the stated one-inch hole drilling requirement when planning installation. Dustproof and waterproof features suit exposed placements, while the clear lens and white light define the selected appearance.

Skip it if you want to avoid drilling; the BooYu Y012 offers suction-cup mounting alongside its brackets.

This is for 12V truck operators who want six concealed white lights and accept drilling for installation. Its multiple mounting locations and directional controls suit a planned hideaway setup rather than a removable dash bar.

#8

8. LAMPHUS SnakeEye III

• Wattage: 11.04 W
• Voltage: 12 V
• Weight: 3.36 oz

Best for: Concealed 12V warning lights.

Why it ranks #8: Four 12V hideaway lights provide 72 patterns, synchronization, and memory recall, though the listed use is a specific amber-and-white configuration.

Four one-inch round hideaway light heads let the LAMPHUS SnakeEye III place warning lights in discreet vehicle mounting locations, enabling a concealed installation rather than a dash or bar setup. The 12V kit offers 72 flash patterns, memory recall, and multi-light synchronization for configurable, coordinated signaling.

The compact one-inch round heads suit buyers seeking a less exposed installation, while their 12V specification defines the electrical system they support. With 72 flash patterns and memory recall, operators can select a preferred signal and retain it between uses. Multi-light synchronization coordinates the heads, and the steady-override function adds a non-flashing option. The set is a four-piece hideaway kit, so its installation approach differs from surface-mounted or cigarette-lighter-powered warning lights.

Skip it if you want a ready-mounted dash bar; the BooYu Y012 includes a dash strobe and multiple mounting accessories.

Choose this four-head kit for a 12V truck installation where concealed mounting and coordinated flashes matter. The one-inch heads and wiring-based format suit a planned hideaway setup, not buyers seeking a plug-in dash light.

#9

9. BooYu Traffic Advisor Bar

• Voltage: 12 V DC
• Weight: 2.4 lb

Best for: Switchable dash warning bar.

Why it ranks #9: This 12V bar includes 162 LEDs, 27 modes, and mounting accessories, but it is a traffic-advisor format rather than a dedicated wig wag relay.

Four switchable color options give the BooYu traffic advisor flexibility to change its warning-light appearance, while 27 flash modes let operators select different signals. Its dual-switch cigarette-lighter control and memory function simplify in-cab operation, and the included brackets and suction cups offer several mounting approaches.

The 162 high-power LEDs provide the light output, while 27 modes and four color options let the operator tailor the signal through the dual-switch cigarette-lighter control. Last-pattern memory saves the chosen mode between uses. For installation, the included brackets support straight or slanted positioning, and suction cups provide a removable mounting route; screws are also mentioned for permanent installation. This 12V bar suits buyers wanting an adjustable dashboard warning setup rather than separate hidden lamps.

Skip it if you need individual surface-mount modules; the Nilight TL-201 comes as four separate lights with a controller.

For a 12V truck needing a configurable dash warning light, the BooYu combines multiple colors, patterns, and mounting choices. Consider it when the bar format and included suction-cup or bracket installation suit your cab.

#10

10. Signal Dynamics Back Off

• Weight: 12 oz

Best for: Brake-light alert module.

Why it ranks #10: This module changes motorcycle brake-light signals; that narrow brake-light application is a poor match for truck wig wag lighting.

Two brake-light signaling modes make the Signal Dynamics Back Off a focused choice for adding wig-wag alerts specifically when the brakes are applied. Its compact solid-state module uses existing brake lights, creating alternating and steady signal sequences without requiring a separate strobe light bar.

Mode one alternates quick flashes before a longer flash, then repeats a short-and-long sequence while the brakes remain applied. Mode two alternates the left and right brake lights, follows with flashes of both, and ends with both steady on. This behavior ties the alert directly to braking, rather than providing general-purpose warning patterns. The sealed, weather-resistant case supports vehicle use, and the stated 10A capacity is an important electrical limit to consider.

Skip it if you need independent warning-light patterns; the Stop-Alert WigWag 36 offers 36 selectable patterns for compatible lamps.

Motorcycle or truck owners seeking a brake-triggered alert using existing brake lights are the intended match. Its two sequences and 10A capacity define the role; choose a separate controller for independent warning lamps.
