Once the headlight assembly is unlocked, press down on the bright locking lever - it is visible when looking straight down from above the headlight.

On the driver side only a portion of the locking lever is visible between the battery and the air box, but you can still reach it with a screwdriver that has a long handle.

While pressing down on the locking lever, push the headlight assembly forward and out of its housing. Careful - it may take a hard push and it might lurch out suddenly.
