you need to replace the fuse for the headlights.
Bad voltage regulator
There is a voltage regulator located on the internals of you alternator replace the altenator. Voltage regulator keeps voltage constant and stops spikes in power output, this is what is causing your headlights to blow.
It might be because of moisture. Mine would go out every time it rained. I had my mechanic put a new silicon seal on the headlights and that solved it for me.
there are several possibilities, first: the fuse that provides power to the headlights could be blown out. second: the headlights could be burnt out. the other possibilities would require a professional diagnostics by a Subaru technician.
left side headlights dim--why?
There are no 2009 Subaru models with 2WD.
When it is raining during the day you should always keep your headlights on.
The voltage is lacking when you are not pressing on the gas... while pressing on the gas.. you are giving the headlights more electricity...
Find out why the fuse is blowing. You have a short or the circuit is overloaded.
Subaru owners keep their vehicles an average of three years.
