CoupeLeicht600

I've been having some issues with my driver's side low beam bulb on my 2002 CL600. I ordered a replacement bulb (Philips OEM D2R) and went to my mechanic. He replaced the bulb, but there's a bit of a yellow hue to the bulb. It lights up and everything. My prior bulb was flickering, and he thinks that I need to replace the igniter. The dealership quoted me $1700 but I'm not going to get ripped-off, so I went to eBay. However, I wasn't sure which igniter to get. Any help or direction is appreciated. Thanks.
