How to prevent the headlight bulbs from blowing frequently

If the headlight bulbs are blowing regularly, there are several possible reasons. Identifying the cause of the problem can save you the cost of continually purchasing a replacement bulb. You need to change them constantly.

Do you use headlight bulbs for a long time?

The typical expected life of a standard halogen headlight bulb is approximately 350-400 hours. Therefore, if you drive a lot on long winter nights, or if you leave your headlights on during the day, your bulb can only last for two hours. Up to 3 months.

It is important to note that when installing an upgraded xenon bulb, it usually lasts only about 200 hours, as it is actually tuned to improve the light output. For drivers who use headlight bulbs for a long time, installing long-life headlight bulbs can shorten the replacement interval.

These more rugged car bulbs contain rugged reinforcements that are three times as long as regular halogen bulbs, yet offer the same lighting performance as regular halogen bulbs.

Are you touching the glass spheres when you change them?

If you touch the glass part of the headlight bulb with your bare hands, a small amount of grease will remain on the natural oil contained in the skin. When the halogen bulb is lit, this oil patch creates a hotspot inside the bulb, causing it to fail prematurely. Therefore, it is advisable to wear latex gloves when installing new halogen bulbs.

Is the bulb wet or suffering from excessive vibration?

Most major bulb manufacturers use tempered glass in their headlight bulb construction, but they are still susceptible to thermal shock. This means that contact with water leaking into the headlight unit is very likely to damage the bulb. It is also important to make sure that the bulb is securely attached. Otherwise, the extra impact or impact on the bulb can damage the filament.

Is the car’s electrical system functioning properly?

When installing the bulb, make sure that the electrical connector from the light’s power lead is securely connected to the metal connector on the base of the headlight bulb. Otherwise, it will be short-circuited and it will be easier to blow off the bulb.

It is also important to make sure that the alternator is not overcharging the battery and that the bulb is not supplying more voltage than designed. The maximum voltage of a light bulb is typically about 13.2 volts.

Are you buying a good quality headlight bulb?

Cheap car bulbs may seem like a good idea, but they usually lack the high-quality, precision components used by major manufacturers such as Osram and Philips, and don’t last long. High quality bulbs are marked with the E1 mark. This indicates that it has undergone the strictest testing and quality standards.
