Odd and unique lighting problem

[didgeridoodude]

Just to be blunt, here's a list of odd things that my lights are doing.
1. left indicator flashes quickly, goes to normal, back to quickly and whatnot on random occasions. I have replaced all of my bulbs, I know that's out of the question.
2. Left indicator signal on the instrument cluster (the green arrow) stays on but does not flash, and when on, the left indicator does not work.
3. Reverse lights haven't worked since I owned the car, nor the fog lights.
4. The rear left brake light doesn't shine as bright as the right rear when my foot is on the brake. Sometimes, the left reverse light may want to work.
5. The light that goes off when the door opens is no longer being sensed unless I manually toggle with the switch but the right door light hasn't worked since I've owned the car.

The problem with your left front indicator/blinker is the bulb. Its in the socket 180 degrees off. Remove bulb, turn 180 reinsert bulb

1. Could be the bulb 180 out like mentioned(front bumper only), or I have found its most likely a flakey connection at the wiring for the front bumper socket.

2. When does it come on solid, when the parking lights are on? When you are on the brakes?

3. Manual trans? Check the wiring under the shift boot.

4. The ground on that side is shot.

5. Your switch is prob worn.
