Why would a headlight keep going out?

Likewise, people ask, why do my headlights keep going out?

First, check the alternator output, as an overcharging alternator will cause premature headlight burn out. Second, the connection at the headlight bulb must be clean and tight. Third, look for any signs of moisture in the headlight capsule.

Additionally, what do I do if my headlight is out? If your headlights suddenly go out, do the following:

  1. First, try your dimmer switch. Often that will turn them back on again.
  2. Try the headlight switch a few times.
  3. Pull off the road as soon as you can and leave your hazard lights on so that other cars can see you.

Also question is, how long should a headlight last?

Typical car headlights typically last somewhere between 500 and 1,000 hours, but there are a lot of different factors at work. Different types of headlights have different life expediencies, so halogen, xenon, and other types can't be expected to burn out at the same rate.
