2003 C240 Headlights
I have found buying each side separately is cheaper and then remember to replace the bulbs right away with genuine 85122's
Any w203 that is no a c55 uses the same headlight.
so here is one side http://www.ebay.com/itm/2006-Mecedes-C-Class-Headloght-Original-HID-Drivers-Side-Left-/331533121467?hash=item4d30e9f7bb&vxp=mtrthen just fine the other
If you go aftermarket I would buy this http://www.ebay.com/itm/USA-DEPO-01-07-MERCEDES-W203-4D-SEDAN-D2S-Bi-XENON-HID-AMG-PROJECTOR-HEADLIGHT-/171734902532?hash=item27fc32a704&vxp=mtrIt is the higher quality aftermarket unit vs the other cheaper ones.
You will need to get the car programed for the xenon lights so they will work correctly.
