i have a 2005 honda accord that i purchased back in nov.2013.
Shortly after buying it the passanger side headlight went out. So i bought a new set. A few weeks later the drivers side goes out even though it was a brand new bulb from the set i bought . Got a whole new set then yesterday the passanger side went out again. tested the bulb and it was no good.

So my question is- What is causing the headlights to blow and how to i fix/find out what is causing them to blow out?

 

Vibration can cause premature failure. Also excess voltage (alternator regulator problem) could cause premature failure.

check mounting for security and suggest purchasing a battery voltage monitor (equus $15) from walmart to monitor battery voltage. It should never exceed about 14.5 volts and usual range is 13.5-14v.

good luck

 

Check the little rubber button-things where the front of the hood closes. Are they adjusted so tight that you have to slam the hood closed?
