The worst a "short circuit" might be blamed for would be the fog light remaining constantly on. I'm going to assume that the replacement bulbs you are using are quality units.

Next, overvoltage would be suspect as a cause of premature failure. Of course a host of other problems would then be present. Absent those, overvoltage is not a likely suspect. AND, since it's only the passenger side, we have to look elsewhere.

Besides overvoltage, the number two killer of bulbs is rapidly turning them on and off. Do you notice any "flicker" on the passenger side fog light?

If so, I would be concerned about intermittent wiring supplying +12 volts to the fog lamp. Next, I'd suspect the ground return for the bulb. That would be the socket and its associated wiring.

Lamp sockets are known to be troublesome on our vehicles. I'd start there.

Regards,
Warren

If the lens is cracked and moisture is getting in there, that's no good either. You'll never stop buying bulbs... Warren's point is well taken also. Make sure you are getting a decent bulb....

Also want to point out, the lense doesnt have to be cracked for moisture to get in. Mine do not have cracks and I notice them fog up every once in awhile.
