Running Light

[ttbikes]

When I have my running lights (64 Tradewind) on my drivers side tail is not on. Brake light works, other running lights work, and blinker works but not the running light. I am not experienced with tail lights so I thought I might ask for some guidance before taking off the light to look. Thanks.

It is probably a dual filament bulb with one filament burned out.

YES. If the brake light works the fixture is grounded. Thus a filament in the bulb or a broken wire to that point in the socket. Most likely the bulb.

I was hopping for that. Thanks I will give it a try.
