A headlight socket basically does what it sounds like – it’s the connector for your headlight bulb. It provides the electrical connection and physically holds the bulb in place. It's got those little contacts inside that actually make the connection, and the shape is specific to the bulb type, so the bulb locks in securely. Obviously, it’s part of your headlight system, which is pretty important. The socket sits behind the headlight assembly. The wiring from your car runs to it, and then the socket passes that electricity to the bulb, making it light up. It's a critical link in getting light from your electrical system to the road. Well, if this thing fails, your headlight won’t work – simple as that. You'll notice if a headlight goes out, naturally. Sometimes it’s the bulb, but often it’s a corroded or damaged socket. Corrosion builds up, the contacts don’t make good contact, or the plastic gets brittle and breaks. It acts like a shield protecting the connection, but that shield can fail over time. Replacing it is usually pretty straightforward, and it's a lot cheaper than replacing the whole headlight assembly. We carry a good selection of these at Fixparts Online, and have them in stock for most makes and models. It’s one of those things that’s small, but makes a big difference when it's working properly. Better than the rest: Socket (MPN 5U0943167) includes a 12-month warranty!
