Hi. Normally LED lights do have an earth wire.If you mean lights for the rear of the trailer or clearance lights then they should be joined into a common earth that then goes to the trailer plug and back to the vehicle earth. The vehicle earth should go back to the battery, not to the body of the vehicle. Hope that helps. Bob.

Yes, you still need to earth the lights.

There is an easier way however.

A complete wiring loom is available for wiring up a pair of LED stop/tail/indicator lights for a trailer. It's available from most auto spares retail shops and there is a choice of two lengths.

The loom is "plug & play" with terminations done with 4 pin plug/sockets at each joint. You still need to terminate the vehicle end with the trailer plug of your choice, but the kit comes with wiring instructions and wire colours are compatible with standard colours as defined in plug wiring diagrams.

I changed my trailer over to LED lights and re-wired using the loom.
Completely waterproof too.

They are earthed in the body of the light and you only have to take the wires back to positive and negative - i.e. you don't have to earth seperately.

You don't say what type of light - presume its a combination type as single light source ones usually have just two wires coming out of them neither of which is earth but they have to be connected the right way around else they won't light up.
