bulb keeps blowing

[Southern Man]

One of the bulbs in the amber running lights that are mounted in thhe front of the aqua shields keeps blowing every few days.

I understand that a short would cause a fuse to blow but what causes bulbs to blow this often.

2008 gl1800 with Chamipon kit.

If it's the same lamp burning out every time I would check to make sure the socket isn't loose and vibrating/jarring the filament when riding over bumps etc. If it was a voltage problem such as too high regulator output I would think more than one lamp would burn out and other symptoms would be evident.

I vote with Greydog.....bad, misfitting, or corroded socket, or serious vibration.

It may sound odd, but check the sockets in all the lamps in that circuit. If one/more bulbs do not have a good ground, it/they use another bulb in the circuit for a ground - that puts more load on that other bulb. In other words the load is put on the weakest link. generally speaking.

[Ol' Grey]

Agreed.......vibration/loose socket or vibration causing a loose socket.

Loner makes a very good point on a bad ground wire somewhere in the same circuit. Running lights, blinkers, marker lights tend to have their own ground wire for each individual bulb. A bad ground from any light in the circuit could cause a problem in a seemingly unrelated bulb........it's called "electrickery" :giggle:

Had a flickering tail-light bulb in an aftermarket tail-light. Found that a cheap plastic brace inside the housing had broken due to vibration, which was allowing the socket to move. I took some styrofoam and cut pieces to shape, then surrounded the socket like puzzle pieces. Bulb still illuminated the lens just fine and no more flickering tail-light bulb.
