do I have to replace the entire headlight, or can I just replace the bulb. The high beam is ok, only the low beam is not working.

ALL BULBS ARE REPLACEABLE ON THE LS. NOW IF YOU HAVE THE XENON PACKAGE UR LOOKING AT ABOUT 350 PER BULB SO MAKE SURE ITS THE BULB.

I have sort of the same question: Ihave a 99 LS 400 and want to replace the high beam bulbs with Silverstar Ultras. How are the stockhigh beam bulbs removed? I attempted their removal but it seems that more than just the bulb needs to be removed so I stopped at that point. Can anyone tell me how to do this?

Thanks in advance for your help.
