Rear side lights work. Reverse light and brake light come on together when I press the brakes. When I put car into reverse with brake pedal down, reverse light comes on and brake light goes off. Anyone know why???
 
The usual, bad or no earth..

+1 - it's always a bad earth - either cos the thing has gone completely open circuit - or like in this case where one circuit has lost its designed / designated earth return, and is therefore "forced" to use another circuit for the return...

bl@@dy 'lectrics! they'll never catch on :rolleyes: ;)
 
I coulda been messing around with that loom all afternoon. The earth wires going to the back of the reversing light bolt weren't earthed, possibly cos of the silent coat black butyl stuff that I'd pierced over the reverse light bolt, albeit a good 6 months ago. I only knew last week when a work friend told me my rear break light wasn't working. When I opened it up it was all melted. Today I was putting a new brake light on. To my knowledge, everything was fine 'til recently. Superstar! Thanx.

Funny that, I did exactly the same thing this morning but for once I did not have an earth issue. My problem was the cheap molding no longer held the bulb in place and with the general vibration of the 110 the bulb popped out even when properly seated initially.
 
I had similar issue - turned out to be cheap bulb holders. Fitted genuine
LR ones and job done.
I know it is an issue. But they last a couple of years before wearing to the point of the bulb working loose and are only a 10min job to swap over. At £2.50 each including a bulb I’m happy with that rather than spending out on more expensive genuine ones.
 
Someone keeps persuading me to do that. On my tratter they'd look terrible. I don't like em.
I completely agree, not in keeping with a vehicle that is older than I am! I keep considering them for the additional lighting I have to reduce the current draw but I am still unconvinced. I also don't like the bright white colour most of the are as well, much prefer the gently golden glow of a halogen.

I only meant side lights and indicators. Still looks original but far superior.
 
I was following a 90's tratter yesterday. It had all the rear lights converted to led but they were the same size and shape as the originals so it looked ok. They weren't the high intensity leds so not over powered. If yer pick the right ones it can be quite a good mod over the originals.
 
I'm missing something still. So brake lights work on their own. When I put the side lights on and press brake pedal, reversing light comes on and the side lights and brake lights go off. I've moved the earth for the one faulty side light and reversing lamp to a different earthing point (which is a good earth). What's going wrong?
