My passenger side bulb keeps blowing about once a month can anyone help me with the problem??

 

What circuit?
Dome light
Headlight

parking light
turn light
front or back?

 

My front passenger headlight

 

Is there any condensation inside the bulb housing? Also what do the wires look like, are they dry rotted, or corroded?

Try not to touch the actual bulb when installing them as well, the oils in your skin can cause them to blow when they get hot, usually the bulb bursts or cracks when this happens however.

 

Bulbs burn out because of heat.
Could be from over voltage heat or lack of ventilation heat.
Yes finger oil on the bulb will create a hot spot, heat again.

Make sure the wattage of the bulb is OEM spec, the enclosure has enough heat dissipation for that wattage.

Check the voltage at the battery, a few minutes after starting, and with engine at about 2,000rpms, should be under 14volts, if higher your voltage regulator is not working.
High voltage is burning out that bulb and will effect other systems as well.

Check the ground wires for the headlights, both sides.
If drivers side ground is corroded then the voltage for BOTH bulbs will be passing thru the Passenger side bulb, this causes higher amps, more heat and burned out bulb.

 

Okay thank you I will try it!

 

I just looked at the bulb housing and it has quite a bit of condensation and the bulb shattered

 

Bulb is getting wet and exploding.

You need a new housing.
