What you can do yourself
- Turn on the lights and walk around the car to find what’s out. Check the brake lights with a helper or by the reflection in a window.
- Replace the burnt-out bulb with one of the same type and wattage.
- If LED bulbs were fitted, the control unit often treats them as burnt out. Use CAN-bus LED bulbs or a load resistor.
