Be sure to check the current source max on the sidecar and compare to the current draw on the LED's
That's what I was thinking. You might want to put a cap in parallel to "smooth out" the pulses. If current draw becomes an issue, you can hook the digital output to a transistor (simple amplifier) and use another power source.
