Has anyone fitted a remote switch to their vehicle? i.e. a keyfob that'll can be wired up to turn interior/work lamps on when not in the vehicle?

Fed up of fumbling in the dark for keys (yes a small torch keyring would prevent this I know) but would also be handy for packing up the fishing tackle in the dark!

Would something like this work?

Thanks in advance...

would work fine, just be careful of the maximum current, use LED lights and you should be fine, make sure it's fused down too.

Awesome, thanks for the pointers.
