Hello, my name is Mark Blocker. In this segment, we're going to cover how to fix a burned-out headlight. Whether you've got the newer style light bulb assembly, that uses actual light bulbs, or the older style that uses a fixed headlight assembly, you can't actually repair a burned-out light bulb. Once the filament inside, whether it be a bulb, or the big cartridge type headlight assembly, once the filament inside is burned-out, that's sealed in a gas environment, and it cannot be replaced, or repaired. The only fix, is to replace the bulb, or replace the headlight assembly. In order to replace a bulb, for example, if you come to the back of the light, once you've determined what light's burned-out, to remove the bulb, first come down, you'll find the socket itself, there'll be an electrical connector. There should be a release on it, that you can push, and release the connector. And on the outer ring, there should be a housing, and if you just slip, turn that ring, counterclockwise, that'll release the latches on the headlight, and allow you to remove the bulb. Like so. When replacing a bulb, you want to make sure you don't touch the bulb itself, with your fingers. The new bulb, because the oil from your fingers can adhere to the bulb, and cause the bulb to burn out prematurely. And to replace a new bulb, use the same procedure as removing the old one. Just slide the new bulb into position, then screw down the latching ring. Tighten it clockwise, that will lock the bulb back in it's position, then reinstall the electrical connector. Now most lights have two bulbs in them, a high, and low beam. Or a daylight, driving light, and a standard headlight assembly. In the other style of bulbs, or headlight cartridge assemblies, you could have two bulb system, with a high, and low beam, or a single dual ulma type headlight. And those that were removed, just by removing the whole light assembly itself, usually held in by three, or four retaining screws on a bezel ring on the front of the headlight. So you can't repair a burned-out headlight, but you can replace the bulb, or headlight assembly itself.
