What is Headlight Switch Replacement?

Your car or truck headlight switch, also referred to as a headlamp switch, doesn't just turn the headlights on and off whenever you want to; it has separate components to turn on each of your parking, curb, and tail lights as well. Most switches also act as the instrument panel light dimmer switch and the interior courtesy light switch. The headlight switch allows you to control all the lighting for your vehicle once you have inserted the key into the ignition and started the car or truck. This allows you to see the road, and allows other drivers to see you. It is better to see, and to be seen, than not to be seen and to hear from other angry drivers. Depending on your model, your lighting controls may be mounted on the dashboard or they may be on your turn signal switch stalk.

How is Headlight Switch Replacement Done?

Most headlight switches are fairly simple to replace. Still, it would be wise to consult a repair manual for your specific vehicle. On older styles in which you pull out a button to turn on the headlights, you will need to access the back of the switch. There is a small 1/4 inch button, usually facing the passenger side of the car. Pull the switch while simultaneously pressing the little button; the switch activation plunger should then come out. Next, unscrew the round nut that holds the switch to the dash. Pull the switch out from behind the dash and unplug it from the harness. Reverse these actions to install the new headlight switch replacement.
