Figure 2: Wiring diagram for the LED Flash Strobe Controller.
- Identify the input and output wires on the controller. The input side is marked "5-24V" and the output side is marked "LED".
- Connect the red wire of the "5-24V" side to the positive (+) terminal of your DC power supply (e.g., 12V battery).
- Connect the black wire of the "5-24V" side to the negative (-) terminal of your DC power supply.
- Connect the red wire of the "LED" side to the positive (+) terminal of your LED strip light or LED bulb.
- Connect the black wire of the "LED" side to the negative (-) terminal of your LED strip light or LED bulb.
- Important Note: If the input and output connections are reversed, the module will not function normally. Ensure correct polarity.
- Utilize the 3M strong double-sided adhesive on the back of the controller to mount it securely on a dry, clean surface.
