Looking for a quick answer. I tried searching but honestly to many answers. I have an 03 MCS with the Xenon (non-projection) headlights. What bulbs do I buy to replace them? H7? D2R? Im confused

 

If you gots xenon and one don't work ....


you gots a problem . . . .

most often the problem is the ballast

but you are not going to find a simple solution at the local AutoZone

go to the dealer and keep one hand on your wallet

ain't them fancy headlights neat??????

 

First step....just swap the bulbs left to right....if the problem follows the bulb, great. If not, then the ballest or the ignitior is most likely bad.
XENON lights, especialy the projectors are great...the others are still pretty good....the long bulb life is nice too.....just buy a quality bulb....the cheapy ebay ones are a low grade....and you will not be a happy camper.....

 

can i just buy a 55w HID kit from DDM Tuning and put those in with new ballasts??

You might need to fab up some parts....the kit is made to fit into a halogen headlight...so the bulb mounting is likely different (the kits bulbs will have a different base), and the wiring is made to plug into halogen wiring..(usuallu from the bulb plug), you don't have that either to plug into....might be more trouble than it is worth imo....

 

You need D2R HID bulbs to replace your factory ones. I only recommend buying genuine Philips bulbs through a trusted vendor, or Morimoto D2R bulbs. I get all my HID components through Matt at http://www.theretrofitsource.com. If your ignitors are good (swap bulbs L/R to check) then you'll probably benefit from a set of new bulbs since HID bulbs do lose output over time (although rather slowly).

 

This ^... If it is the bulb replace both. The new one will look brighter than the old one.

Yes they sure are!!!!
