hi there......I have an 04 CL55 and a 07 E350 and I noticed that both cars have similar front lights.......however at night the E350 smaller cirlce lights on the inside of the larger lights seem to be xenon or something like it as they look like the xenon's they are next to.......on my CL the smaller circle lights appear to be old non xenon's and look pathetic next to the xenon's.......I really notice them now because I had my bulbs replaced under warranty.........and man they look as blue as the sky............so is there anything I can do to get the other ones to look similar? thanks in advance for any advice.
