Why aren’t my brake lights working?

Hello, if the high mount lights illuminate, then your concern is isolated to the lamps themselves, not any trigger for the lights to turn on. Remove the affected bulbs, replace them. Make sure you have the correct application of bulbs. If that doesn't fix it, you'll have to check for power at the sockets and trace wiring back to where power is lost. www.repairpal.com/repair-shops
