Brake light comes on after brakes installed
It is also to alert you that there is insufficient brake fluid, the parking brake is on or you have a problem with the EBP system (which has to do with the rear brakes).
All of this is in your owner's manual.
If that is the case, then disconnect one sensor at a time and see what happens. That way you will know what wheel it is. If the sensors were not installed correctly or of poor quality that could be the problem
