Reverse lights not working

[MHunter]

I can't seem to get my reverse lights to work, on my USA spec GTR. Is there a way to test if the reverse switch on the G50 is dead?

I have the green & green/brown wires connected to the reverse switch. Switching them around doesn't help.

I've had problems with mine too. I took the switch out and tested it by pressing a screw driver in the end. Mine worked when I didn't screw it in all the way but now its stopped working again. Go figure. The switch isn't faulty, but seems very sensitive. Hopefully others can weigh in here with some sage advice.

In the UK we have to have rear fog lights so there are no lamps left for reverse so there will be no prior experience to tap.
The wiring implies that the switch does not earth anything so it should not matter which way round the wires go.
Anyhow, Green is ignition switched live so the first thing is to check it is live with the ignition on.
Connecting Green wire to the Green/Brown wire should put the reverse lamp(s) on with the ignition on.
If you now connect the green to the switch the other pin should now have +12v on it with reverse gear selected. If not then either the switch is faulty or perhaps wrongly adjusted.

Thank goodness you said that Steve, I looked at the title and thought "oh no, I don't think mine have ever worked!!"
All is clear now, I don't have any!

I bought two indicator lenes with the clear lens below and wired the gearbox switch to the nearside to make a reversing light and put a red high power LED bulb in the offside for the rear fog.

I figured out the problem. the 2 red/brown wires on the rear fog/reverse lights were inverted in the loom. I really should stop assuming the loom is correct whenever I get an electrical problem and trace the wires first.

Still, thanks for the replies!
