What does a Headlamps Bulb do?

A car has two headlamp units at the front of the car. These usually have 4 or more light bulbs that provide the car's light beam. Dipped and main beam are selectable on the indicator stalk; . The dipped beam is used for everyday purposes as driving during evenings and night. The main beam on the other hand is used when significant lighting is required to see the road ahead adequately. Importantly, the main beam is only used when driving alone as to not blind other motorists temporarily with these intense light beams.

Newer cars often make use of LED lighting in some form which are practically maintenance-free. Bulbs on the other hand are prone to deterioration over time and can fail. That said, when the lights do not work properly it can be the case that there are other issues with the headlamp unit. The units usually have a seperate fuse each which can fail too, it is therefore advisable to check the fuses first before replacing a bulb. Other bad electrical connections can be caused by damaged wires or lamp sockets.

Considering the risks of driving without functioning headlamps it is important to have the defective headlamps inspected timely and professionally and, if necessary, have the bulbs replaced.
