Hello Kurt, first off there is only 1 fog lamp in the rear so it does not confuse drivers to think that the brakes are being pressed, now as for the head light what i suggest to do is to take the drivers side bulb and ignitor and swap it to the passenger side and vice versa, that will tell me a lot if its the headlight module or not, if the passenger side still does not work after swapping the light and ignitor then the module that attaches to the headlight unit under neath can be the issue,. most times they got corrosion into the module and caused issues such as this. and the whole bumper needs to come out to remove and check the headlight module, you may be able to access it from underneath that one may have room, i think its the drivers side that you have no room to work with.
