Hey all. So in the past three months, I have gone through 3 headlights. It seems they are burning out for no apparent reason. When the first burned out, I replaced both sides (OCD-I didn't want one brighter than the next) and all was fine. Then the opposite side from the first burned out (even though it was a brand new bulb as well). So, I replaced just the one that was out this time. Now, the other light went out (the first replaced). I use my XV twice a day,. back and forth to work (50mi total), so they aren't on long. The one that burned out this weekend, did so while parked for 3 days (and not on). Have any of you ran into this problem? To me, it seems to be an electrical problem because no way should bulbs burn out every few weeks especially with the limited use of them. Any help would be appreciated.

This is happening to me on my Tribeca. The lights were great for 3.5 years then one went out. No big deal its almost 4 years old so I changed it. A few weeks later the other light went out. Now a few weeks after that the new one went out.

I have been very careful not to touch the bulb each time as that supposedly causes early failures. But next time I'm going to use latex gloves just to be 100% sure. I'd bet a shiny new nickel that its something going wrong during install.

It is actually the correct procedure to replace them in pairs.

Schonuff brought up a good point. Are you making direct contact with your skin to the bulbs? The bulb surface is not to be touched by direct contact with human skin. You can touch the part that will connect to the connector, but not the bulb surface itself.


If that's not the cause of concern, then perhaps you may have either the terrible misfortune of getting bad quality/bad batch bulbs or some other underlying issue.

Where would improper voltage come from? All the voltage runs through the battery fed from the alternator. I would think if there was an abnormal voltage the computers would have issues before a resistance load like a lamp. I think.

I'm thinking the same kind of mindset, since the XV Crosstrek does use a Body Integrated Unit (indirect control of circuits).

The link I added tells where the improper voltage could come from. Just giving the poster some other idea's other than the oily finger reason.

Fulling understanding what is being discussed in that article, I believe I am still correct and the conditions described in that discussion are in theory correct but in reality probably not likely. Each his own and good luck with your search.

It might be a problem with the harness. There could be a wire loose or otherwise damaged. I was having this problem with the HIDs on my old car and I bought a new harness which corrected the problem.

I wonder what bulbs the OP is using?

I agree that mishandling the bulbs during installation is the number one cause of premature failure. I always wear gloves and use alcohol to clean the bulb with before installing.

Did you notice any moisture in the housing? An old seal that starts leaking trace moisture can cause issues over time. Condensation settling on a hot bulb could blow it. I had this issue with another car and had to either reseal the housing or buy a new housing.
