Abstract: A replaceable headlamp assembly for use with a vehicle comprises a bulb socket and a locking member, wherein a flange of the bulb is held in position at the bulb socket by rotating the locking member. The locking member has a resilient section which snappingly engages over a key of the bulb socket to lock the locking member to the bulb socket while also permitting the locking member to rotate relative to the bulb socket over a given range. The locking member cannot be inadvertently disengaged form the bulb socket and therefore cannot be inadvertently lost or misplaced.

A dual adjustment device is provided for effecting the up-and-down or vertical adjustment and also the left-to-right or horizontal adjustment of the headlight assembly.
