here's whats going on... both of the bulbs in each of my tail lights turn on when i turn on my lights. however, when i press the brake, only 3 of the four bulbs become brighter. i can't figure out what is wrong. (btw, the brake light indicator on my dash has come on because of this problem). Anyone have any ideas?

 

sounds to me like the bulb is burnt out, as these bulbs are kind of like a high and low beam set up ie dual filiment for parking light and brake light, if I where you I would change the bulb and go from there, if its electrical you'll know, if a brand new bulb does the same thing then you might be looking at a trip to the dealer, hope this helps

Same thing happened to me. Dealer fixed it under warrenty in about 15 minutes.

Good luck,

mine does the same thing its the far rear passenger side one, parking lights work fine but the brake light wont light up and ive replaced the bulb twice now. im just going to have to go to the stealership and see what wrong.

 

hahaa..damn...i have the same problem....wonder if my extended warranty will cover it?

 

what year tl's does everyone with the problem have, mines 03 tl-s

 

i had that happen on my 00TL , another common glitch in the TL , love it or leave it

 

its not a problem, its just the bulb has burned out...cost $4 at any auto parts store and takes 2 minutes to replace them.

 

no big deal.. one of ur fillaments burnt out.. bulb cost 2 dollars and takes 5 minutes to replace

 

it's really easy to do it yourself. bulb# is 7443 for the lower ones and 7440 for the top-mount

 

no mine keeps blowing bulbs everytime i put a new one in, parking lights fine, hit brakes boom blown bulb

 

then you have a short. have you tried replacing all teh bulbs at once

 

try another brand bulb?

or you can try swapping the bulbs that work to see if its the plug and not the bulbs?
