LED Work Light
Affiliate link — we may earn a commissionAn LED work light on a cordless tool is a small diode near the chuck or blade that illuminates the work surface when you pull the trigger. Most modern drills, impact drivers, and saws have one built in. The light kicks on a moment before the motor starts so you can see where you're about to drill or cut. Some tools keep the light on for 10 to 20 seconds after you release the trigger. Higher-end models have a dedicated light button so you can use the tool as a flashlight without running the motor. The brightness varies from barely useful to genuinely helpful depending on the tool.
Why It Matters
Dim corners, inside cabinets, under sinks, and inside walls are where you use tools the most. A built-in LED is always aimed at the cut line and doesn't need a free hand to hold. It's a small feature that makes an outsized difference in usability, especially on impact drivers where you're working inside electrical panels and junction boxes.
