2004 Hyundai Elantra: side only..headlights..side low beam..bulb

Resolved Question:

What could be the cause of frequent and sudden headlight failure on one side only of my 2004 Hyundai Elantra? The car has gone through a set of headlights at least every six months since purchased new in 2004. Now, the driver''s side low beam burns out as soon as it is turned on with a new bulb.

For around 15 bucks or even less you can pick one up

Chances are you regilator is gone and you have over voltage

This is the only thing that would take that many head lights out

The rest of the lights are more giving than a head lamp

With the meter on and the car running you should read around 14 volts
