Hi guys,

I need help, the side marker bulb and the parking bulb on my '05 LS430 keeps going burning out. I replaced the parking bulb several times already but every time I put a new one on, after about 15 minutes it goes off... I'm afraid this could be a big electrical problem...

The driver side is ok never had a problem with it. I even took the good bulb from the driver side and put it on the passenger side but after about 15 mins. it went out. Inspection of the bulb shows the filaments broken/burnt out.

Any help would be greatly appreciated!

 

Did you check the inside of the socket for corrosion or bent contacts? Also, check the connections behind the socket, if you can access it.
