SL/R129: Headlight bulb replacement
There is a beige/grey plastic panel directly behind the headlamp housing. It's secured by a clip. Pull the clip off... upwards. The plastic panel needs to be fully removed, and pulled out. Be careful that the rubber seal stays intact, and realign it if it comes free. Pull off the wiring housing. The bulb is secured by a wire harness clip. Squeeze it together and free it from the bulb. The bulb will come free and there is just enough room to pull it out. Replace the bulb.....but not with H1's....damnit!
Put the whole thing back together and get back to the shop for a pair of H4's.
Best wishes
