Started out of nowhere. no brake lights wen driving untill i turn headlights on then brake lights stuck on as if im braking fully. Break relay perphaps help appreciated.Drive a taurus se 95- thanks

 

Can you do this? Check your signal lights ft & rear without the head or pkg lites on. Then watch them with the head lites on. Unless you have separate lites for signal and stop lites you should see something unusual going on. Sometimes a filament in a bulb from the tail lite system will wind up on the stop/signal lite element and give the weird results you are getting. It could be a faulty bulb. Let me know if you find anything. Thanks,,,,,,hanky
