1.Wear gloves when touching the bulb

Protective gear is important during repair and installation for your safety. It prevents direct exposure to harmful chemical elements. When doing headlight repair, your bare hands should not handle the bulbs, particularly if it is halogen type. Thus,  you should always put on latex gloves.

2. Remember to loosen the headlight bulb strainer

In most cases, the strainer holds the bulb in the correct place like the high and low beam position. The bulb’s high beam should always face down so it can shine up and vice versa for the low beam part in halogen lights. During maintenance, slacken the strainer (commonly threaded) so that the bulb comes out easily after unplugging the connectors otherwise it will spoil.

3. Use bulb grease appropriately

During maintenance, use the headlight bulbs grease under the rubber and the ring that seals the bulb in the housing. You can also apply the grease properly on the connections. It keeps them clean and free of moisture and corrosion. When applying the lubricant, ensure it does not touch the bulb because it will cause a hotspot. And it will make the bulb blow early. In case the grease touches the bulb by mistake, wipe it out with a clean cloth soaked in alcohol.
