SuzukiSavage.com - Tail Light Out

greenmonster Senior Member Offline Hellooooo Nurse! Posts: 420 Vancouver BC Gender:	Tail Light Out 02/09/18 at 12:26:35 Hey folks, As the title says, my tail light is out. I have a brake light, and the bulb is good. (tested that out with several known-to-be-good bulbs) When I check the voltage, I have good voltage coming to the tail light, using the socket as ground, but no light. Does the tail light and brake light have different grounds?

Aren't the tail light and brake light the same bulb? One filament for the tail and one for the brake. If there's voltage in the socket, it would have to be the bulb. I have not checked mine in the bike, but that's how it is in my truck.

What i do is partially insert the key before it bottoms out. Before this I would only get brake light. Just turn the key while not putting it all the way in.

Are you talking about the license plate light vs the brake/tail light?

Did you check the contacts?

They do corrode.

Posts: 420 Vancouver BC Gender:	Re: Tail Light Out Reply #8 - 02/09/18 at 15:05:11 So I don't know what changed from the last test I did until the test I did just 30 seconds ago. Now I have good signal on my brake light(12.5V), but almost nothing on my tail light(0.1V which could almost be residual) for voltage. Sounds like a hinky wire. Anyone know which colour that one is?
