The WRS-1097 LED Light for WRS  or WRC-400 technical cameras is used to illuminate the distance, aperture, and shutter speed scales on the lens when you are using the camera under low-light conditions. This LED light magnetically attaches under the accessory mount and sits above the lens on the camera body.

The LED module has two different modes, the demonstration mode, which automatically shuts off after two seconds and the constant light mode, which simply turns on or off with the push of a button. In addition the brightness of the LED can be controlled by holding the button down.
