Towing Lights

Why Towing Lights Matter

Whenever you hitch up a trailer, tow a car behind an RV, or flat tow a vehicle on a road trip, the vehicles behind you need to see your brake applications, turn signals, and running lights clearly — just as if they were watching the tow vehicle itself. Towing lights bridge the electrical gap between your tow vehicle and whatever is being pulled or carried, ensuring that every driver on the road gets the same visual cues that keep traffic flowing safely. In most states and provinces, functioning towing lights are not just common sense — they are a legal requirement.

Types of Towing Lights

The towing lights category covers several distinct product types, each suited to a different situation:

• Magnetic Mount Towing Light Kits – Portable units that attach temporarily to any metal surface, ideal for occasional towing or towing vehicles without permanent wiring. These typically include a pair of DOT-compliant stop/turn/tail lights and a wiring harness that plugs into your tow vehicle.
• Hardwired Trailer Light Kits – Permanently mounted lights designed for trailers, boat trailers, and utility trailers. LED versions offer sealed, waterproof construction built to withstand regular submersion and road debris.
• Diode Wiring Kits – Used primarily in flat towing (dinghy towing), these kits splice into a towed vehicle's existing tail light wiring so that brake signals, turn signals, and running lights from the motorhome are relayed to the towed car's lights without feeding back into the car's own electrical system.
• Bulb-and-Socket Wiring Kits – An alternative flat tow lighting solution that adds extra bulbs inside the towed vehicle's tail light assemblies; these draw power from the RV, so the towed car's battery is not consumed.

What to Look for When Shopping

Start by identifying your use case — are you towing a trailer regularly, or flat towing a car behind a motorhome? Trailer kits and flat tow kits are not interchangeable. Next, consider the connector type your tow vehicle uses (4-way flat, 5-way, or 6/7-pin round) to ensure compatibility. For trailer lights, look for DOT compliance and weatherproof or waterproof ratings, especially if you haul boat trailers. For flat tow wiring, verify that the kit is compatible with your specific vehicle's taillight design — some modern vehicles with LED taillights require dedicated LED-compatible diode kits. Finally, wireless and battery-powered towing light kits offer a no-run-wire convenience factor for truly temporary use.
