Why is my anti lock brake light on?

The anti-lock brake system is a complex configuration of computers and sensors. When all of the components are working in perfect harmony, it ensures a quick, reactive system that can improve braking control under all surface conditions. Faults in this system are often first indicated by illuminated lights in the gauge cluster.

Replacing a socket is as simple as snipping the old wires and splicing in the new unit, which is typically an inexpensive part to purchase. If you keep these tips in mind, most brake light problems will be easy to diagnose and fix on your own.
