Bought for my MDT. The USB port in the MDT does not light up steadily while driving. We need to fix the same to prevent the movement of the light. If it turns off while driving, you'll need to reset it and go back to settings to get back to the red light. Decent light for the price but needs fixing the light in addition to connecting to the MDT. It's a great light for personal use when you don't need to move or drive.
