OK I checked all my rear bulbs and they work. Applied the brake and still all of them work. Now after driving for more than 10 minutes the "Brake lamp" light comes on. What else can it be.

 

a bulb. Pull each one out and double check.

 

great...

 

they sell our special 3 dollar bulbs in a convenient $6 2 pack because whichever one is out- the opposite side will die soon
I bought 2 packs and replaced them all to be done with it

Did you check the 3 rd brake light- in the rear window- you access the bulbs from inside the trunk

Maybe its a vac leak

 

i replaced all mine cuz i had the light too. and now its just weird, sometimes the barke lamp light goes on, sometimes it dosnt. and when it is on, seems like everything is lit. oh well.

 

possible early warning of brake light switch failure? just guessing

or bad ground wire connection that gets jostled

 

Same issue.

 

there has to be a filament in one of the bulbs tot working correctly causing the light. For teh price id just start replacing bulbs till it goes away

 

The brake fluid level float could also be working improperly. That's what happened with my '02 TL-S. $150 parts + labor to replace it.
