Leaving lights on all throughout the day and the night can prove to be impractical and costly. And this is not just true at home or in the office, but also in automobiles. Wiring a vehicle's lighting systems, such as the headlights, directly to the battery will make them work even during high-visibility conditions and they may send wrong signals to approaching motorists. That is why switches for these different applications are made to break the flow of current and allow you to control their usage. Among these switches is the headlight switch.
This switch prevents your ride's headlights from being automatically turned on when you start the ignition. (It's the ignition switch that allows the all electrical components to receive electricity supply.) The headlamp switch also serves as the driver's primary control over the headlights, allowing him to turn them on and off whenever he wants to. And since some headlight switchs are designed to control the turn signals as well, it also makes for an efficient and space-saving component on the dash.
In some vehicles, the headlamp switch is situated on the steering column; while in others, it is placed on the dashboard or instrument panel. This switch may come as a push-button type with a beam-like symbol on its knob matching the headlight indicator on the instrument cluster. It may also come as a rotating knob similar to those on the stove. It is usually bigger than other lighting switches to ensure easier visibility. The car headlight switch is also wired to a relay, which is the direct safety breaker of the current flowing to the headlight. This means that when the ignition is started, the relay regulates the voltage amount going to the headlight but will not light it up until the headlamp switch is turned on.
Unless you only drive during the day, your ride's headlight switch is probably one of the most used buttons in on your dashboard, making it a bit more prone to wearing than the others. If you're lucky, you might not need to replace this switch in your car's lifetime. But if you're not, well, there are always many aftermarket replacements available on the market. Just be extra careful, however, because not all headlight switches are of high quality. When selecting a replacement, verify the product number through the manufacturer and stay away from imitations. To get the exact part for a particular vehicle make and model, refer to your car's specifications. Doing so will make you get a direct-fit component that can be easily installed.
