On the backside of the bulb socket, click the release lever down (as seen in the video). This will allow you to remove and replace the bulb

Pull the old bulb end (which rests just above the previously mentioned release level) up to remove it

Push new bulb end down until it clicks into position

Do not touch the glass of the new bulb with your hands during installation. Oils from your fingers can overheat the glass and cause premature failure .
