Review on 🚦 iJDMTOY (1) 12V Wired Control Module with Solid, Strobe, and Flash Features - Ideal for Car, Boat, and Household LED Strip or Bulb by Tony Francis

Many e-bikes supply a sufficiently high voltage to light up that a voltage regulator must be used (SMAKN DC 4.5-60V to 1.25-30V Lm2596hv step-down supply Voltage Switching Regulator Module Step Down) to set the operating voltage for this module to 24 volts or less. I set the voltage to 15 volts (my battery supplies 52 volts) and placed this module in line with the existing LED. It works like a champ, offering numerous lighting options depending on your flash speed and duration. It remembers your last settings, which is a great feature.
