The Main Run Cable of the LED Autolamps Trailer Harness System 6.7 Metres, Waterproof, Tool-Free
Product Overview
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, running the lighting signal between lamps along the trailer's body. Unlike the short 5C550C stub cable used for gooseneck lamp connections, the 5C670C is the long-run cable designed to carry all five lighting signals tail/marker, LHS indicator, RHS indicator, brake/stop, and earth, the full length of the trailer from lamp to lamp.
Suited to trailers from 3.7 to 12 metres, the 5C670C uses 100% waterproof plugs and tinned copper conductors throughout, with accessory wires for connecting 2-core marker and licence plate cables along the run. No assembly tools are required, and the system is designed to cut installation time by up to 70% compared to traditional wiring methods. Backed by a 5-year warranty.
Features & Benefits
-
6.7 metre length — provides the main wiring run between lamps on trailers up to 12 metres; longer than the 5C550C stub cable, which is designed for short gooseneck lamp connections only
-
5-core configuration — five conductors carry all standard trailer lighting signals: tail/marker, LHS indicator, RHS indicator, brake/stop, and earth; a single cable covers the complete lighting circuit
-
100% waterproof plugs and cables — sealed against road spray, rain, and submersion throughout the full cable run; critical for boat trailers and agricultural trailers regularly exposed to water
-
Tinned copper wiring — corrosion-resistant conductors maintain reliable conductivity over time in the salt and moisture environments typical of Australian trailer use
-
Accessory wires for 2C marker and licence plate cables — built-in branch provision allows 2-core marker lights and licence plate lights to be tapped off the main run without separate wiring loops
-
No assembly tools required — plug-and-connect installation saves up to 70% of wiring time compared to traditional trailer harness methods
-
Suits trailers 3.7m to 12m — covers the full range of Australian light trailers, caravan setups, and boat trailers within the LED Autolamps small harness system
-
5-year warranty — LED Autolamps' standard warranty applied to this cable

Frequently Asked Questions
How is this cable different from the LED Autolamps 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 specifically for gooseneck lamp connections. Both are 5-core and waterproof but serve different roles within the LED Autolamps harness system.
What role does this cable 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 (like the 5C550C) then branch off to connect individual gooseneck lamps.
How much cable do I need for my trailer?
At 6.7 metres, this cable suits the lamp-to-lamp run on most trailers up to 12 metres in total length. The number of cables required depends on your trailer's lamp positions and configuration.
How many cables are included per pack?
The supplier lists this as a "Pack" but does not specify the quantity included.
What are the 2C accessory wires 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 time and keeping the wiring neat.
