How to replace headlight on 99 buick riviera

Hello. I happen to own a '99 and had to do the same. You can access the back of the bulb by removing your air filter and hose. This will free up room for you to reach the bulb.

Find a way to get your hand on the back of the headlight assembly from under the hood. Depress the tabs on the socket on the rear of the assemble and rotate counter clockwise then unplug the defective lamp replace with a new one being careful not to touch the glass on the new one with your hands or anything oily.replace the socket and turn clockwise until tabs lock.
