Causes of headlight failure
Headlight failure can happen for various reasons. Some common causes include:
Worn Out Bulbs
The most frequent cause of dim car headlights is burnt-out bulbs. Headlight bulbs have a limited lifespan, and they eventually wear out and stop working. Vibrations from driving on rough roads or extended use can contribute to bulb failure over time
Problems in the electrical system, such as faulty wiring, blown fuses or issues with relays, can lead to headlight failure. Corroded or loose connectors can disrupt the electrical connection between the bulb and the vehicle’s wiring as well. This makes car headlight bulb replacement of prime importance.
Flickering or dimming headlights
Dimming or flickering headlights could indicate voltage fluctuations, often caused by problems with the alternator or voltage regulator.
Damaged Lens or Housing
Cracked or damaged headlight lenses or housings can expose the bulb to moisture, debris and other environmental factors that may lead to failure.
Physical impact, such as hitting a pothole or being involved in a minor collision, can cause the filament in the bulb to break, resulting in a burnt-out bulb.
Excessive heat due to a malfunctioning cooling system or poor ventilation can cause the headlight bulbs to overheat and fail prematurely. That said, you may browse through these car lighting parts for sale in the UAE to replace the existing ones.
