I have just installed euro lights on my 300CE. WOW. They look great. However, the reflector lens appears loose when the cover is off. Does it lock in place when the rear cover goes on???

The lens is held in place by tabs on the front of the light assembly that snap over the edge of the lens.

Good luck,

The headlamp adjuster thingey had come loose. Reconected everythings back to normal, I think.
As for choosing Bosch/Hella or the grey market imports I recomend paying the extra and getting the real deal. Mine are DEPO which are OK but you can see the differance in the quality and FIT.
