What is the LED on the cordless impact driver?
| Some cordless impact wrenches have one or more built-in LEDs for use in dimly lit areas. |
 | LED stands for Light Emitting Diode and is simply a small white or colored light source. LED lights come in many shapes and sizes, but the size shown on the left is commonly used on a power tool such as a cordless impact driver. |
Where is the LED light? | |
 | The number of LEDs in a cordless impact driver and their location varies by brand and model. Some models have a single LED indicator located under the chuck or on the tool handle. |
 | Other models have several LED indicators located around the cartridge. They are often referred to as "halo rings". More lights mean a brighter workspace, and being at the front of the tool means they're closer to the screw or hole you're working on. |
How to turn on and off the LED | |
 | How you turn on the LED light may vary depending on the brand and model of cordless impact driver, but most are turned on by pulling the speed control trigger. Typically, the LED indicator stays on as long as the trigger is pulled, and on most models turns off as soon as the trigger is released. |
