my plate light doesn't come on via park lights on / Head Light On any pointers or ideas what can b the problem ?

 

Check the wiring, maybe the previous owner installed a backup camera and left wires disconnected.

 

Bulb burned out or possibly corrosion on the bulb housing or terminals?

 

Replace the bulbs, no reason to assume it's anything else!

I suppose it's corrosion cuz the housing had a lot of dirt on it. Including the wires and what not but all power works .. I jus have to do all t10 bulbs swapped out

 

I put my park bulbs in the plate lights and turned on all lamps nothing still

 

cleaned it got it on wit some leds

 

Congratulations, you did it! LEDs work best! I ordered high output LEDs for my backup lights from our sponsor, they wouldn't stay in the socket. Parts mgr at Infiniti gave me a new bulb...I saved $80 sending the LEDs back!

Incandescents bulbs are so 2005 Gary. Get your car a nice set of bulbs from Diode Dynamics!

 

That's exactly who I ordered those LED backup lights from at $80= a pair, they wouldn't stay in the socket and I turned them every direction possible. It's a major PIA to take tail lights out only to discover I couldn't get the new LEDs to work!
