MagicShine MJ906S Test / Review on a Trek Rail 7

The reviewer discusses the Magicshine MJ-906S bike light, which is designed to be wired into an e-bike system. He explains that out of the box, the light is not in e-bike mode and can draw too much power, causing the e-bike system to shut down. He had to put it into e-bike mode by holding the button for eight seconds. In e-bike mode, the light outputs about 2800 lumens on high, which is less than its maximum but still bright. He praises its build quality, brightness, and price, though he notes some issues with cable shadows and the light being always on when the bike is powered on.
