Make sure your pedal returns all the way back. There is a hall-effect switch that just sees the metal from the prake pedal go away and tells the footwell module to turn the brake lights on. As a backup, the DSC also will turn on the brake lights if it sees pressures above a certain threshhold. You may have to check for codes - brake pedal switch implausible, something like that.

You may just have a bad switch or more likely the pedal is unable to return all the way to the switch.
