We recently acquired a 2007 460. When I pulled up to a store front I noticed that the low beam on one side was not working. No "bulb" indicators had come on to warn me. later I checked and it was on. Seems to do as it wishes but it does not activate the warning system. Anyone else encountered this problem ? Thanks TNSC

 

That's a typical sign of wearing out bulbs. Need to replace the bulbs. See here for the how-to: https://www.clublexus.com/forums/ls-...completed.html. Buy this OEM replacement bulb: Philips D4S bulbs (part # 42402C1).

I have to agree. Same thing happened to me after purchasing my car. Here's the link to the bulb.

I had the same problem.. unfortunately my LS was clipped in a parking lot just after the passenger side bulb failed. On the bright side.. (no pun intended) I provided the body shop two bulbs for their use.. and they used both as the un-damaged side bulb died before they were done with the body work.

Now I just need to figure out how to replace the foglight bulbs... inside my garage because the neighborhood association has just this year... banned working on your car in the driveway =P

Peace out.
