Best Prices for High beam is not working Inspection

Common reasons for this to happen:

The lighting system in your car is relatively simple, but there are several things that can go wrong with it. While the problem is most often the bulb itself, it can also be the fuse, relay, switch, or faulty wiring.

Blown bulb

Like any bulb, headlamps have filaments that provide the light used to illuminate the road ahead. Some systems use a single multifunction bulb that can switch from high beam to low beam. Other headlight systems use two halogen bulbs in each headlamp -- one for high beam and one for low. None of them will need to be frequently replaced, but they won’t last forever either. Some experts recommend replacing all headlight bulbs or filaments at the first sign of failure, particularly if they are original equipment. Replace all filaments, not just one at a time.

Blown fuse

The main job of a fuse is to protect the electrical circuits in your car from a shorting or overloading. They are rated by their amperage and are designed to blow or open when the current being drawn through it exceeds its design rating. If a device draws enough current to blow a fuse, you've probably got a more complex problem somewhere else in the system that will cause the fuse blow again, sooner or later. Occasionally, fuses will fail for no apparent reason. Many modern headlamps have one fuse per headlamp. If it is burned out, change it. If it’s not and the low beams work, the problem is more likely the switch, relay or wiring.

Bad high beam relay

By definition, a relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current. In a car, there are lots of small, low current relays that are used to activate larger, higher voltage components. A relay bridges the gap between the two, making it possible for small currents to activate larger ones. The high and low beams will have their own relay. The switch is only used to energize the relay, which then provides full power to the headlights.

Malfunctioning high beam control

This is the device that “switches” between high and low beams. In modern cars, there is a switch lever on the steering column that a driver either pushes or pulls to switch between high and low beam headlamps.

Faulty wiring

The wiring has a break in some point in the system, stopping electricity from getting to the relay, switch or headlamps.
