简介

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.

    • Apply a small amount of solder to the tip

    • Wipe on a damp sponge

    • Touch the tip of the soldering iron to the led solder to liquify it

    • Apply solder wick to absorb solder

    • This guide uses a desoldering pump instead of desoldering wick. The wick would work better.

    • Warm up the trace on the circuit board and the LED lead with the soldering iron

    • Wipe your soldering iron on the damp sponge every time you pick it up

    • Apply solder to the lead until the hole completely fills with solder

    • Reassemble by following the teardown in reverse order

    • You now have a customized bike light or a working LED!

    • We replaced the middle LED with blue and the two outside LEDs with white. We set the bike light on the last mode. Enjoy!

    • Certain colors of LEDs may be illegal as rear bike lights. Use at your own risk or for a different application!
