Turn off the vehicle and open the hood. Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old 9006 LED bulb counter-clockwise to remove it, then insert the new bulb and reassemble.

Can You Put LED Bulbs in a 1999 BMW 318ti?

Upgrading to LED is one of the most effective ways to modernize your BMW's appearance and safety profile. We recommend starting your upgrade with the 9006 LED low beams, as they see the most use. Adding a matching 9005 LED LED kit later will complete the look and ensure consistent lighting performance. Because BMW utilizes a CANbus system, standard LED bulbs may cause "bulb out" errors on your dashboard. Always opt for "Error-Free" or CANbus-ready kits which include the necessary resistors. Don't forget the H1 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
