daverclasper Posted June 22, 2016 Report Share Posted June 22, 2016 Hi folks. Went to a classic show at weekend. A bloke who parked next to me, reckoned my front indicator was very dim as I was following him. Didn't seem too bad to me but not sure. I think I checked and cleaned the lenses and reflectors a bit back. Do bulbs need changing after a while regarding this anyone know. Advice much appriciated. Cheers, Dave Link to comment Share on other sites More sharing options...
John Bonnett Posted June 22, 2016 Report Share Posted June 22, 2016 Dave it is almost certainly a bad earth and nothing to do with a dirty reflector or the lamp. Link to comment Share on other sites More sharing options...
dougbgt6 Posted June 23, 2016 Report Share Posted June 23, 2016 Yes, likely bad earth. My bulbs are 40+ years old! Never had one go and they are bright enough. Good idea to bypass the night dim relay, if you have one. This dims the rear bulbs at night, surprisingly. Link to comment Share on other sites More sharing options...
daverclasper Posted June 23, 2016 Author Report Share Posted June 23, 2016 Cheers Could that flasher unit earth as well a bulb earths (any other earths do you know please). Cheers, Dave Link to comment Share on other sites More sharing options...
dougbgt6 Posted June 23, 2016 Report Share Posted June 23, 2016 Dave, not quite sure what you mean? I don't know what car you've got but on some there are different models of bulb holder. One has two connectors, Live and earth. The earth connector goes to a dedicated earthing point. If you've got that, the earthing point is where to check. The second type has one connector for live and relies on the metal body of the holder earthing to the body of the car. This last one is the most troublesome, if that's what you've got either clean up the area around the holder or consider changing to the two connector holder. Also a good idea to check the earthing strap from the battery, they can look fine but may not be! Link to comment Share on other sites More sharing options...
daverclasper Posted June 23, 2016 Author Report Share Posted June 23, 2016 Cheers Doug that's useful What I was wondering (not knowing quite how flasher units work) is if the flasher unit had a poor earth, would this affect power to the bulbs.

Peter Truman Posted July 1, 2016 Report Share Posted July 1, 2016 I know this won't be the problem but I was following my son in his Jap sports car and both his rear flasher/brake light were dim. I immediately thought of the earth, so when he got home I checked all the earths, but they were good, so I checked the bulbs, some one had fitted 24volt bulbs. This particular car has a tendency to relatively frequently blow its rear bulbs a problem with the model maybe that's why the 24v bulbs were fitted, not by me?? Just shows what can happen at a service, by a reputable manufacturer. Peter T Link to comment Share on other sites More sharing options...
