4 Steps to Fix a Low Beam Headlight Bulb

Find the blown out bulb

When you are driving at night, you can tell if a headlight bulb has blown out. If one beam is not as bright as the others, this might mean that the bulb has blown out. Some cars have one bulb for both high and low beams, while other cars have different bulbs for high and low beams. 

If only one side of the car has a problem with the light, you can replace the blown out bulb. It is not necessary to replace the bulbs on both sides of the car if only one side is not working. If both high and low beams are not working on the same side of the car, it might mean that there is a problem with your car's electrical wiring.

Buy the replacement bulb

The type of bulb you need to buy to replace your car's low beam light depends on the year it was made and the model. To find out, take these details to the automotive parts store so that the clerk can give you the correct bulb.

Get your tools ready

Replacing a low beam bulb can be more work than you expect. Sometimes you won't need any tools, but in other cases you will need special tools to remove the bumper and the headlight. You can find a list of all the tools you might need in your car's service manual. 

However, most cars just need a screwdriver or no tool at all to get to the headlight housing. After reading through the service manual, inspect your headlight to see if it looks like the one in the manual. If it doesn't, you might have replaced some of the screws with flat heads screws when you bought it used.

Disconnect the negative terminal on the battery

Before you disconnect the battery, make sure you know where your blown out bulb is. Once you disconnect the battery, the headlights will go off. Use your hand or socket wrench to loosen the nut holding the negative terminal of your car’s battery. 

You do not need to remove it completely. Make it loose enough so that you can be able to slide off the cable from the terminal. Fasten the cable on the side of the battery so that it doesn't reconnect to the terminal when you are working. You don't need to disconnect the battery's positive terminal as there is no circuitry with just the negative terminal loosened.
