I was replacing all my headlamp bulbs today and I noticed there are two sets of bulbs in the DRL area for my 04 LS430. We replaced the xenons, and then we went to replace the 9005 bulbs, but there are two MORE bulbs directly above the 9005's. Are these T10 bulbs? We couldn't get them to come on no matter what we tried. What are they for? Here is a pic
It's called Clearance Lamp. It should come on when you turn on the low beam (9005 is off). Of course when the low beam is off, the 9005 is on at half power to provide DRL functionality.
I installed a set of PIAA bulbs I purchased on Amazon.com
Take a look at Post #2. Those PIAA bulbs look pretty good.
ok thanks. Do they need to be yellow like that? They looked clear for the OEM ones.
What are these bulbs supposed to be doing in terms of functionality if the low beams are already turned on?
rkw's DIY's with custom pictures are really quite good. And, he has PDFs of pages for specific DIY fixes straight from the Lexus shop manual. rkw is a valuable resource to CL.
