To whom this may concern I'am so so sorry it was not my brake light it is my antilock light.
antilock on 1996 Buick Century
probably a sensor failure. take it to a shop and let them pull the code and tell you the issue. the traction control is tied to the abs so when it is repaired, the traction system will be good.
put on computer ck codes it will help you find out what problem is
