This little piece basically does exactly what it sounds like – it holds the headlight bulb securely in place. It also provides the electrical connection to power the bulb. It’s usually made of a heat – resistant plastic or similar material. Sometimes it includes a rubber boot or seal to keep moisture out. It’s part of your headlight assembly, obviously. It slots right into the housing and keeps everything lined up correctly. The bulb sits inside it, and the whole thing then bolts or clips into the headlight itself. It’s not something you generally see, it’s tucked away inside the headlight. Well, if this thing fails, your headlight will stop working. It might be intermittent at first, flickering or going on and off, but eventually, you'll just have a dead headlight. It acts like a shield, protecting the bulb and making sure the connection is solid. You’ll notice if one goes bad pretty quickly, especially at night. They can crack or corrode over time from heat and exposure to the elements. You can find replacements pretty easily—Fixparts Online has a good selection. It's one of those things that's inexpensive to fix, but really important to keep working correctly for safety. Technical support included: Bulb Holder (MPN 1T0945331) comes with a 12-month warranty!
