Введение

The bike light in this guide is sold under various brand names, but in fact is a no-name brand and comes with no distinct markings on the packaging. Some uses for this guide are replacing broken LEDs and customizing the LED colors. This specific guide customizes the LED colors, but the process for replacing them is identical.

Note the type found here does not have a brand name on the device and are sold under various fake brand names.
