It started with my left map light burning out. Then a month later, the front left headlight burnt out. I checked the bulb and the filament was definately gone. Then about 2 weeks later the left fog went out. Is there a reason why all the lights on the left are burning out?

 

Your car is a liberal?

 

are you using crappy eurolite bulbs? - they always do that.
are you using over-wattage bulbs? - these will get ridiculously hot and actually melt the glass bulb.
is your headlight harness fried?

 

No, no aftermarket lights yet.
No, "
No, neither that or fuses.

 

know when the last time they were changed?

 

I have had the car a year , and never changed them but I imagine never. I just thought it was weird that none of the right are dim or dying.

 

have you tried replacing the bulbs to make sure its not a wiring problem? could just be a very strange coincidence that all of them went out on the left.
