1. Loose wiring connection
Because of loose wiring, the flow of electricity to the contact point with the bulb will not be quite right, and will actually cut off, and back on at fast intervals. The constant on and off will cause the bulb to get heated up.
2. Contacting the bulb with your fingers while installing
There is no question that halogen bulbs become very hot. So, when you feel the need to replace and touch them with your hands, they become very dirty. Bulbs need an evenly heated surface so that they can last for a longer time.
3. Poor quality of the bulbs
Cheaper bulbs are nowhere near the standard high-end bulbs. The filaments on the bulb are made from a very thin tungsten gauge, which might fail in no time if the quality is not good. Vibrations are the common causes that make these cheaper bulbs fail.
4. Excessive vibration
The halogen filaments inside the bulbs can’t withstand excessive vibration. Therefore, check the retaining springs that hold the bulb and double-check whether they are tight and secured. Also, it is good to check the suspension springs, wheel bearings, and wheel balance so that they don’t cause major vibrations.
5. Condensation inside the headlights
One thing a lot of people run into, is additional condensation (which can actually be solved ). Because of excessive condensation inside the headlights, there could be electrical shorts.
6. Faulty voltage regulator
A voltage regulator is an important piece of electrical device for a vehicle. In short, it limits the maximum amount of voltage that flows through the whole wiring system. That way, it provides a safe and usable amount of electricity for the components to use.
Conclusion
So, those were the reasons why your car’s headlight keeps on burning out. Watch out for the signs and regularly check them when you are visiting for your car servicing.
