A common 1200 problem for the tail lights.

The ground wire that connects to the rear bumper bar bracket in the boot area. If this is dirty, or badly earthed, then your tail lights will not work properly.

Almost all of those problems are ground related. Check wires that are attached to the body.

I am attempting to rebuild my Lb110 coupe with little knowlage about cars. I have found some electrical problems. When i have the head or parking lights on and then turn on my hazard lights they alternate on the front and if i hit the brake i lose my right brake light. Also it has resently developed a problem were if i turn the key to start the car everything goes out and then comes back dimmer then before with out the starter turning over. I was wondering how to best trouble shoot and fix my problems.
