I've own my G35 for about 6 months, and I've noticed on of off (more often when it was winter) that my Passenger Daytime running light located above the headlight bulb and my passenger dome light cut in and out, I'm not sure if they are just burning out or if its an electrical issue. I just find it odd that they are both on the passenger side.

Thanks for any help
Unsure if anyone has posted about this issue, I'm new sorry

 

could be a fuse or the wiring is the same for that side

 

Try changing the bulb. My passenger side HID used to cut out, got new bulbs and installed them and I haven't had that problem.

 

Swap the bulbs, if it follows the bulb replace that bulb.
