Genuine Makita 620557-1 — LED circuit board (work‑light PCB) designed to restore the built‑in illumination on compatible Makita brushless impact drivers. This compact printed circuit assembly contains the LED(s) and control components that power and switch the front work light so the tool lights reliably when you pull the trigger.
The board is a rigid, surface‑mounted PCB that plugs into the tool’s existing wiring harness and sits behind the front housing — a direct replacement engineered to fit without modification. It’s intended to replace failed or flickering work‑light circuitry and returns consistent, bright illumination for locating fasteners in low light.
Example models that commonly use part 620557-1 include Makita DTD153 and DTD154 series impact drivers and several XDT13 / XDT14 variants (examples: XDT131, XDT13R, XDT14R and related XDT13/XDT14 models). If your tool’s work light has gone out or blinks, this genuine Makita component is the straightforward power tool parts fix that typically brings the light back to life.
Simple to swap in with basic hand tools — remove the front housing, unplug the old board and reconnect the 620557-1 — it’s an original Makita replacement built to the same fit and electrical specs as the factory unit.
