The bulb for mine is replaceable - if you can find it. GM has discontinued it. It plugs in twists. I got several bulbs at the junkyard. This light is always lit, as soon as you turn the key on, the bulb has a dim glow, this is a safety feature so if your in a dark parking garage or at night you can see where the headlight switch is.
