Maybe someone can help me out. I just bought a 2007 g35x sedan. I have a tail light not working, but its only half of one side not working. Its the inner circle on the pass. side that is not lighting up. Anything I can check out first? I am handy and I will take out the whoel tailight soon, but just thought someone would have the answer before I try to figure it out. Thank you!

 

Sounds like you're in the market for a new taillight.

 

Aside from disassembling the taillight, the LED's are not individually serviceable. I had a single LED flicker on one of my lights, ended up buying a good used one and swapped it. I'd buy new or ask for a picture of the tail light illuminated before purchase to verify full operation. Best of luck!

 

You can get the complete assembly at amautoparts.com for just under $60. I just replaced the driver's side. Fits, looks and works perfectly. Comes with 10 year warranty. See link below
