The LED Autolamps 5C670C is a 6.7-metre 5-core lamp-to-lamp cable that forms the primary wiring trunk of the LED Autolamps trailer harness system. 100% waterproof plugs and cables, tinned copper wiring, no assembly tools required. Accessory wires for 2C marker and licence plate cables included. Suits trailers 3.7m to 12m. Five-year warranty.
The 5C670C is the main run cable in the LED Autolamps trailer harness system, carrying all five standard trailer lighting signals tail/marker, LHS indicator, RHS indicator, brake/stop, and earth from lamp to lamp along the full length of the trailer body. At 6.7 metres it covers the lamp-to-lamp run on most trailers up to 12 metres. Accessory wires built into the cable allow 2-core marker lights and licence plate lights to be tapped off the main run without separate wiring loops. Waterproof plugs and tinned copper conductors provide reliable, corrosion-resistant performance in road, salt, and water environments. No assembly tools required. The system is designed to cut installation time by up to 70% compared to traditional trailer wiring methods.

What is the difference between the 5C670C and the 5C550C?
The 5C670C is the 6.7-metre main run cable that carries the wiring signal between lamps along the trailer body. The 5C550C is a short 550mm stub cable for gooseneck lamp connections. Both are 5-core and waterproof but serve different roles in the LED Autolamps harness system.
What role does the 5C670C play in a trailer wiring setup?
The 5C670C is the trunk cable it runs the full length of the trailer, connecting lamps along the run and distributing all five trailer lighting signals from one end to the other. Short stub cables such as the 5C550C then branch off to connect individual gooseneck lamps.
What are the 2C accessory wires on the 5C670C used for?
The 2C accessory wires allow 2-core marker lights and licence plate lights to be connected directly off the main 5-core run without running separate wiring loops to each fixture, saving installation time and keeping the wiring neat.
Does the 5C670C require any tools to install?
No assembly tools are required. The 5C670C uses plug-and-play connections for fast, tool-free installation.
Is the 5C670C waterproof?
Yes. The 5C670C has 100% waterproof plugs and cables, suited to boat trailers and agricultural trailers regularly exposed to water, salt, and road spray.
