When you're heating water with LP gas, the red light typically does come
on while the burner is trying to light.
If your water heater happens to decide to have a heat cycle while you
happen to be looking at the switch you will see it light briefly.
Also it's possible the wind did blow out your burner and the heater
re-lit. Again- if you were looking in the right direction you would see
the red light come on for a couple seconds and go out.
If the light comes on and stays on, it means you have a fault and need
to cycle the switch off and back on to clear it and let the WH try to
Short answer, the light coming on briefly is normal and nothing to worry
