How to Correctly Treat and Install New Headlight Bulbs

By Ethan Melandri

Are your headlights burning out more quickly than you believe they should? There are plenty of causes for why your headlights may be ending their life early. Once you identify the issue you can save yourself money because you do not need to replace or change the bulbs as frequently.

The Times You Use Your Headlights Affect their Usage

The life of an original halogen light bulb is typically 350 to 400 hours. If you do a lot of driving during the winter, at night, or have your headlights on during the day you could be using your lights up in two to three months.

Its important to note that if you have fitted upgrade xenon bulbs they will normally last only around 200 hours, because they have been in effect tweaked to improve their light output. For drivers who do use their headlight bulbs for long periods you can reduce the amount of time between changes by fitting long life headlight bulbs.

Heavy duty components for headlights, which last longer than regular halogen bulbs, provide you the same performance as halogen bulbs.

Are You Touching The Glass Bulb When You Change Them?

Glass bulbs are very sensitive. If you touch the glass during the changing of the bulbs your skin's oils are getting on the light, thus leaving a residue behind. Halogen bulbs have what are called hotspots when oil is left on the glass. This hotspot will burn quicker and thus the light will fail. You should always wear gloves, like latex, when changing out halogen lights.

Moisture or Vibration Affects Light Bulbs

Light bulb creators for vehicles do use a heavier glass when they build headlight bulbs; however there are still some areas where the glass can be more vulnerable. For example thermal shock is when the bulbs meet water, which leaks into the headlight unit, thus ruining the bulb. You do need to make sure the bulb is correctly replaced, and ensuring it is secure and protected from jolts and bumps to avoid damaging the filament.

Is Your Wiring System Correct?

The connectors in the headlight holder are electric. They are the source of power from the battery to the bulb, and these metal connectors need to be properly secured to the base on the headlights. If this does not occur a short circuit or blown bulb will result.

You also want to check that the alternator is not providing too much power to the battery, which offers a higher voltage than the bulb can handle. Volts for a headlight bulb are 13.2 as a maximum.

Are You Buying Good Quality Headlight Bulbs?

Saving money can be important; however buying inexpensive headlight bulbs results in lower quality components. Osram and Philips are two top manufacturers of headlights providing durable and quality materials in their bulbs. You want a quality bulb that has the E1 mark, which shows the rigorous testing and standards they have been through. - 21396
