Driver Side aftermarket headlight stopped working, the power steering and passenger window doesnt work

I bought after market halo lights and they both worked fine for some time but the driver side stopped working. The low beams of both lights went out first along with the power steering. So I have to use the high beams. When I remotely lock the car the headlights flash. When I remotely unlock the car the driver side does nothing. I checked all the wires and fuses and even bought new bulbs and reassembled the light. When the power steering went out it went on and off for a whole day but has not worked in months along with the light which went out afterwards. The passenger side window will not roll down and has been that way for months as well. To me it seems like all the electric in the car is going to crap. Please help me this is getting worse every day. The trunk will not pop open like it is supposed to the back doors do not lock or unlock remotely. I have no clue what is happening with this car it was brand new.
