ive searched and searched and searched...
hey guys i have a problem. searched this site. searched google. tell me if you think my theory is correct...
my onboard computer is telling me "left auxiliary bulb on" and "right auxiliary bulb on". from my knowledge, this means my left and right tail light bulbs are not working and my auxiliary bulbs are acting as backups.
when i turn my car lights on, the upper corner of my tailight housings are lit up. is this the "auxiliary bulb"? and if so, which bulb is normally supposed to act as my tail light?
according to the owners manual, i believe its the light toward the bottom closer to the center of the car.
i hope that's easy to follow...please help!

It sounds like you are spot on. Change the main bulbs and you should be good?

I suck at the internet! 
Anyway, go to the forum page, and click on "search this forum", then type in "auxiliary bulb" and you'll get all the info you need. Search is your friend.
I will not delete the thread. This is how people in the future find stuff. If we deleted everything that was answered there wouldn't be much knowledge in the forums.
