Don't know if this would work as I don't have a Preditor motor to check. But how much voltage is available at the kill lead with the engine at speed? The kill lead is the small wire that attaches between the ignition module and off and on switch and is grounded to kill the engine. Kill lead voltage has been used to operate lights from a magneto system in the past. Would be interesting to know if the voltage is compatible to operate lights if it didn't cause the coil to misfire or shutdown at speed. Or worse, blow the bulbs!
