Tail lights...

[Blaze45]

I recently purchased a pair of LED tail lights. They are a combination yellow turn and red stop. Interestingly enough, the lights come with four wires. A white (ground), red (brake), brown (park) and a green/yellow (turn). I don't recall ever seeing a tail light with a separate brake wire. Since the tow vehicle is four wire, this should be an interesting hook-up. Any ideas? Thanks...

I discovered from a friend who works at an RV repair place that I need a converter.

In the US, the rear trailer lights are generally red with two intensity levels. Dim red are marker lights and the bright red are signal lights. This only requires 4 wires -- ground, marker (dim), right (bright), and left (bright). If there are only 3 wires, it is probably relying upon chassis ground (attaching it to grounded metal.) The stop function is achieved by turning on the right and left functions steadily and at the same time. I believe with the light that you have purchased, it requires 5 wires because the turn (amber) and stop (red) functions are separated -- ground, marker (dim red), stop (bright red), left turn (amber), right turn (amber). Here again, if you only have four wires, it could be relying upon chassis ground. Many cars are lighted this way, so I'm fairly sure that it is legal, however, it is unconventional (at least in the US) to wire a trailer this way.

It is definitely possible, but you will need a minimum 5 wire connection to your tow vehicle (yellow/green from your description must be kept separate) and make sure that the tow vehicle is sending the proper signals.
