TD5 Rear Reverse Lights Wiring

Hi All

Looking for some help with wiring up some work light / reverse lights onto my 2002(52) Defender TD5 110 CSW.

I've got 2 x good quality LED lights which I am planning to mount high up either side of the rear door to shine down & back and a MUD OEM style dash mounted control switch which I want to use to control it.

Ideally I'd like to have it so that when the switch is depressed then when I select reverse they will come on so that normally the switch is left on and triggered by going into reverse. This will mean I can use as work lights by knocking the transfer box into neutral and also means I won't forget to switch them off when I come out of reverse etc.

Mud have supplied a wiring loom diagram for the switch (attached) but I would have thought pin 86 should be an earth and also not sure where my feed from reverse lights to trigger switch would fit into this?



Looking for some advice on how best to tackle this and if anyone has done something similar that has any handy do's or dont's on doing it!

Any and all help/advice would be welcome!

Thanks

Looks like that is a diagram for using the switch to switch on additional driving lamps that come on with main beam.

If I were doing this I'd use the reverse light live to activate a relay to switch on a live to your switch, and then take the switched live from your switch to power the new rear lights.

Relays do vary in terms of which pins do what, so consult the instructions that came with it, or some of them have a little diagram embossed on their casing showing which pins activate it and which ones carry the load.

Cannot see the logic of having a switch when using the reverse switch but here's one way View attachment 205341

In the above diagram, the switch's tell tale light will be on all the time, as it's being fed by an ignition-switched live.

well spotted

I wired up my LED flood light directly to the existing reverse light. When I select reverse, it comes on. Simple. I also wired in an isolation switch for the flood light so I can isolate it for normal driving conditions and MOT tests etc. I’m not saying it’s the best option, but it’s simple and works for me.

I would use a three way (on/off/on) switch fed by a permanent/ignition live (your choice), and the reverses switch live. That way you can either have it on with reverse, off, on as work light. that is how I have wired mine up. it is always set to be on with reveres but I can use it as a work light without needing to be in reveres when needed.

I would have liked to do that, but it’s a bit more complicated!!
