Switching to magnetic, cordless lights is one of the easiest ways to eliminate wiring headaches when towing a boat, utility trailer, RV dinghy, or farm equipment.
Are wireless trailer lights legal on public highways?
Yes. Wireless trailer lights are legal for highway use as long as they satisfy standard traffic lighting requirements including visibility, color, placement, and required brake and signal functions.
To be road-legal, trailer lighting systems must meet safety criteria such as FMVSS 108 in the U.S. or CMVSS 108 in Canada.
Mandatory Functions: Running lights, brake lights, turn signals, hazard flashers, and rear reflectors.
Correct Colors: Red for tail/brake lights, red or amber for rear turn signals, and white for license plate illumination.
Symmetrical Placement: Lights should be mounted at matching heights on rear corners.
Adequate Brightness: Lamps must remain clearly visible during highway driving.
Mount on Clean Steel: Magnetic bases require direct contact with solid steel surfaces.
Use a Steel Safety Tether: Secure lights with a safety cable to prevent accidental detachment.
Monitor Battery Levels: An in-cab dashboard monitor helps track battery life and signal connectivity.
Seal the Weather Cap: Keep rubber charging port plugs fully sealed against moisture.
RV Flat Towing: Replicate motorhome signals without modifying factory wiring.
Boat Trailers: Reduce wiring corrosion caused by water exposure.
Agricultural Equipment: Move lighting systems between equipment easily.
Utility & Rentals: Add temporary legal lighting solutions.
Yes, provided they meet standard color, brightness, functional requirements, and remain securely attached.
If your trailer displays a rear license plate, local laws require illumination at night.
Yes. Non-functioning tail lights are a violation regardless of the reason.
