2006 Honda CR-V. Haven burned through 9 headlights in 2.5 years. Fuses are ok. Both lights burning out. What's causing this?

Luke:
One thing that can make a big difference is if you are "touching" the glass bulb with your bare hands. I ALWAYS wear rubber gloves when replacing anything electrical and also use some dielectric grease on the snap in part. Other than that, you could be having a short somewhere.
This could also be down to a bad battery as some owners have solved their issues..
FlagMichael:
The big sleeper in persistent headlight failure is engine mounts. They harden and the vibration gets to the headlight filaments. Try setting a plastic cup of water on the radiator cross-member when the engine is running and compare the amount of ripples to a similar car.

When I worked in avionics I went to an autopilot school, and they told us of an autopilot a customer had brought in because it was porpoising (constantly pitching up and down) and nobody could fix it.They finally tracked it down to hardened mounts on one of the engines; the vibration was driving the artificial horizon gyro nuts.

Timbo is here:
Cheap bulbs
Bad connections
Water ingress
Fingers touched the bulb glass during installation – the small grease deposits cause hot spots
Fuses protect circuits from overload so I guess it is not that.

Hi at a guess faulty body work rust and poor connections.
