Tail light issue - fuse?

[rocketpants]

Hey guys,

I have sequential taillights, and they've worked fine for a couple months now. However, now when I have all my lights on, if I make a right turn signal, only the middle bulb flashes. The other 2 bulbs (the far left bulb, and the far right bulb), will stay lit, but not sequence (blink). My left taillight is completely fine though, and sequences as normal.

Is this a fuse issue, or a bulb issue? I would imagine it be a fuse issue, because the bulbs still light up, so they obviously aren't burnt out.

Any help is appreciated! Thanks in advance!

Did you ever figure out this issue? I have a similar problem where only the first and third light blink when turning. All lights work though

OP's post is fm 2010 & hasn't logged-in since last summer (Jul 2023). My guess, for you, is to look @ wiring harness b/c if lights are illuminating the fuse isn't bad. These aftermarket connections are prone to corrosion as they're not sealed very well.

Whenever I swap anything electrical, I seal all connections w/ silicone and/or liquid tape.
