How to Replace the LED Work Light on a DeWALT Miter Saw

The cut-line work light both lights up the base of the saw (for better visibility) and provides accurate blade alignment for cuts. At the heart of the cut-line is an LED light. It is secured in a housing with a lens and a wiring harness that connects it to the power supply. Over time, the LED will burn out and the work light will need to be replaced.

Let's get started.
