Suzuki GS750. 78. I have a strange problem with the rear light. After fixing a brake switch I set up the new headlight and put everything back, to test. Everything works . Except! When I switch on the lights the rear light may not come on, if it is tapped very lightly on it comes and wont go off, until switched off. I oiled the spring, cleaned the contacts, even soldered more on to the end of the bulb connectors to increase contact. It's such a light touch it needs, that I think I could leave it, and the first rev or movement of the bike would put it on. Brake lights work on same bulb. Any ideas?
Is the bulb a snug fit in the holder? Sometimes it’s necessary to squash the holder in a little so it holds the bulb firmly. Can’t think of anything else unless it’s a bad earth?
It looked good really clean so I didnt clean it. @Yorkshireman I just sandpapered the connection and its working as it should.
