Hey guys,

I noticed that one of the 3 brake lights on the left side goes dark when I step on the brake. It lights up fine when the headlights are on and stays lit but doesn't go bright when I use the turn signal. I tried replacing the bulb but that didn't fix the problem.

Any idea what's wrong?

It's a 'two part bulb'. It does driving lights and brake lights. So one part of it is dead. New bulb needed.

Do you have a test light or VOM so you can check the bulb socket or unplug the light harness and check it at the connector? If it's just the one bulb giving you trouble I think it would be isolated to the taillight harness. Do you have sequential turn signals?

I don't have a test light but yes I do have sequential turn signals.

If it's the second or third bulb I'd make a wild guess it's trouble with the harness.
