Hi
My new brake light has just a red and blue wire.
The old one that I am replacing has a red, black and light purple wire.
How do I connect the new to the old?
I assumed it would be red to red and blue to black leaving the purple redundant?
Many Thanks

I think you old light would have been a combined rear and brake light that why it had three wires. Look at the bulbs to confirm, the old one would have two connections on the bottom and the new one only one.
Hard to find the original Lucas dome. Its better than what was there anyway, some flimsy oversized plastic dome with no rubber seal hanging off by one screw LOL.
As for the electrics in my car, would find more sense in the Bermuda Triangle! Still haven't got my interior light and Horn working
There has been a number of posts about horns and interior lights not working
search for Horn Stopped Working and Wiring interior courtesy light. These may give you a starting point
The other common factor between horn and interior lights is that they are both switched on the return (earth) side, unlike anything else on the car. This can be puzzling at first for anyone who isn't aware, and hasn't had a look at the circuit diagram, and these people probably keep fuse makers in business when they fault-find.
Thanks, got my original Lucas lens and also two new rubber sockets from the David Manners group.
Sorry but I am still non the wiser with horn/light.
Lets start with this question
Where is the fuse for horn and interior light?
Assuming a standard loom... main fuse block.
Input/ power is a Brown wire ( from Control box )....... feed to Horn and Interior and Door / Courtesy lights Is a Purple wire.
Put your Multi meter ( 20 volts DC range ) on the Brown wire and a good earth... to establish that 12 volts is getting to the fuse first of all.
Disconnect the battery and then remove the fuse, clean it up with sand paper / emery paper and test it Multi meter on Ohms this time to establish that the fuse is good.Clean the fuse holder clips and remove any rust / dirt.
With 12volts present and a good fuse to these components you will be on the right tracks. Re connect battery and test horn and lights.We'll see how you get on.

Hi
Thursday night 9pm and my car wouldn't start in the works car park. I called RAC and after 30 mins of waiting they informed me I had a flat battery. They jump started it and it got me home.
Put new battery in and low and behold the horn is now working, so is the interior light but the only problem with the light is that I cannot switch it off so I have simply removed the bulb until I can work out why.
Horn is ok it now turns "On and Off" at the touch of a switch.
Cheers
Mark
