I ordered a reproduction DuoLamp Tail Light from St3iners last fall, and I’m finally getting around to installing it. I can’t get the light to work, so I may be doing something wrong.
Here’s what I've checked so far:
1. I have a good ground at the light housing, and at the outer shell (grounded portion) of the socket. I checked for continuity from the housing and grounded portion of the socket to the negative post of the battery.
2. I have voltage to one of the two pins in the socket. It's a dual-filament bulb and socket, but I only hooked up one wire, since I only need a tail light, not a turn/brake light.
3. Both halves of the bulb test good - I have continuity from each of the two posts on the bulb to the grounded part of the bulb.
4. The bulb only fits in the socket one way, and it looks like the bulb should be making contact with the pins in the socket.
5. BUT: the bulb doesn’t light.
Is there a secret to the spring-loaded socket in the tail light?
Both headlights, and the rear worklight, all work fine.
Thanks for any help.
