So I scavenged rear reading lights from verada at the wreckers with the intention of wiring them in to my TH Exec. i can't see any loom (not surprised) that would suit it, so I'm doing it the old fashioned way, by running wire from the drivers footwell (where my dodgy footwell and door courtesy lights all come to a junction..) to the rear lights.

Basically I want the lights to come on with the dome light (when a door is opened) and go off when it is off. BUT, I want to retain the functionality of them being able to turn on at any time with the use of the button.

Using LEDs which means the set up has to be polarity sensitive. I had a fiddle just before and it seems strange the way it works, I would have thought that by connecting both coloured wires to positive and the black to the negative I would get constant light (regardless of button position) and if I connected only one (forgot which one) I would only get light with the button in the on position. This doesn't appear to work as intended.

Has anyone achieved this? Is it because I'm using LED's which are polarity sensitive?

Cheers.

The Verada lights will have three wires coming out of it .

two switch ones and the power.

Okay ,to allow it to work from your rear doors independently of your main door circuit ,here is what you can do.

Take the positive wire from your boot light and feed it to both lights.

Earth one of the other wires and see that the switch on the light works ,if it doesn't ,swap the other wire to make it work.

If your TH is like mine ,then the rear door only has the one trigger wire to work the front lights.

Rather than re-pin the rear switch ,go back to the wreckers and get two front door switches as these have two wires coming out of them.

Replace your rear switches with these new switches and splice one wire into the existing loom and then take the other wire up to the light.

This way ,you will have the rear lights work independently when you open the rear doors and working map lights when the doors are shut.

and led have nothing to do with how you are trying to work it.Its the way the light is set up.

Cheers.

That's almost on the money Maggie but I'd like them to come on with any door, like how the dome light comes on. I take it on the Verada's respective door activates the light (LH turns on the LH door etc) but I'd like the option to have all 3 (dome, RH, LH) come on if I so desire.

Then you will be able to run the door wire from your interior dome lamp.

Actually the rear ones as far as I can tell on my KJ2 light up both for any door. They're just treated like all the other interior lights.

Yep that is correct, Unless you have a KE and possibly a KF when they only come on when the door is opened. IN the case of the door switch, it is totally possible to repin them, I have done it to run the wire back into the door for the rear courtesy lights.

Interesting. I'm not quite sure which method I like more...
