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

I set this switch to light up my headlights so drivers can see me while I'm clearing driveways in my area. I'm really impressed with this one and its compact size but should have read all the other features it has. I can change the flash speed, flash control and so on with the built in red/black wiring without messing it up. For the price, it's worth more than its weight and wealth of features.

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…

There is no documentation for this device. I have a couple of LEDs that are already grounded and I have no idea if this will work - I don't want to try it as a check said the device was damaged due to a bad connection. If I connect it according to the label, IN-V and OUT-V are electrically connected through the LED. If that works? Will it damage the device? I could add an optocoupler and power my LEDs with +12V, but then I could just build my own circuit from scratch.
