Tail Light Switch problems of the 2013 Subaru Outback

Have replaced the low beam h7 bulb 5 times this year and has even blow less than 1 hour after fixed by a Subaru dealership. Tail lights have been replaced 3 times in 8 month. High beam lights 3 times in the past 12 months. Fixtures twice. Charred from extreme amp spikes in wires. Now to top it all off entire wiring harness for passenger side is out.

Repeated lighting failures on exterior lights all around car. Have replaced headlights, tail and side lights repeatedly at my cost. Some completed at dealership, some completed at home after cost too much.

Upon noticing a blown 3rd tail light(one of the tail lights on the rear hatch/door of the wagon,) I disassembled and found that the sockets on both sides(left and right 3rd tail-light sockets) were scorched around where the bulbs fit into them. The discoloration was brown/black and was present not only on the socket with the blown bulb but also the other, working side. Dealer replaced blown bulb and made no comment on scorched bulb sockets. It almost appears as if they were so heated they were ready to melt or burn the plastic. Car has been in service for 27 months and has 27k mostly city driving on it. Happy to provide photos of the affected sockets to anyone investigating or concerned.
