Interesting question. Bulbs do burn out, but premature failure is often caused by overvoltage from the alternator. Have your dealer check the alternator for correct voltage AND waveforms. You can check it yourself with a multimeter. If the battery voltage is more than about 14.5Vdc, eg 15+, the alternator has to be replaced.

Does seem odd,never heard of Subaru having that odd habit.
I would have thought your dealer would have checked but if not have them or someone check the charging system output.

Probably a blown fuse if it happened all at the same time, unless you went underwater or in outer space.

Generally, it is better to replace both at the same time, simply because the possibility of the other one following after. BUT $150.00? wow, that is not something that would void your warranty if you replace it yourself. The bulbs are as cheap as $7.00 at your local parts store. Save yourself $130.00 and replace them yourself. ^^ Good luck and hope this helps. P.S. If you are talking about the entire headlight assembly, then $150.00 is more than fare.

That far up might be your radiator, seems you might have a split coolant tank or near the metal crimp and its pushing past the sealed area. without pictures of the area you are refering to ill need more discrition to help out.

Could either be a bad switch or connection. Check with voltmeter to see if the bulb socket is getting continuous power. If it isn't, check power at switch and wiring.
