I recently cleared and upgraded to some LED switchbacks for my 08 TL headlights and they have been working wonderfully up until last night after driving in some pretty hard rain. As of now my driver side blinker amber LED's only work sometimes, however, the white ones work with no problem whats so ever. I'm really at a loss because I know the amber ones worked before last night and worked for a couple minutes today but now the bulb stays constantly white even with the blinker on. I did notice however that once it became night time and the auto headlights switched on the hid's the blinker worked fine for a bit but when I put a light on the daytime sensor that the bulb no longer would flash amber. Has anyone had this problem before and found a way to fix it? is there a possibility I just have a bad bulb?

 

What switchbacks are you running?

 

Probably crappy bulbs

 

I bought the switchbacks from endlessrpm a couple weeks ago.
Here is the link for them: 7443 Switchbacks with resistors (set) - EndLess RPM

 

RMA the bulbs, try switching from driver's side to passenger to rule out the circuit being the culprit, but my gut still says bad bulbs

 

Do you have any recommendations for some 7443 switchback bulbs?

I also wouldn't use resistors, I'd do this instead:

Okay, thanks so much I appreciate the help I'll look into this and hopefully get everything sorted by the end of the week!
