    • Warm up the soldering iron

    • Tin the tip of the soldering iron

    • 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.

    • Place the new LED through the open holes

    • The LED should cover the schematic symbol on the circuit board and the flat edge of the LED should line up with the tip of the diode symbol shown by the arrow

    • If the LED does not stay, you can tape it in place on the opposite side of the board

    • 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!
