The LED lights on the Dino-Lite USB can be toggled on/off through the DinoCapture 2.0 or DinoXcope software (except the AM211 / AM2011 / AM2111).
If you are using a Dino-Lite with a third-party application, that application may have a “Camera Settings” window which may allow you to control the Dino-Lite LED lights.
If the third-party application does not have an option to control the lights contact us for a LED control tool which will allow you to toggle the lights independently of the software.
