Abstract
A dual operational and stop light control for adapting combined stop and turn signal lights on a trailer to independent stop signal and turn signal lights on a towing vehicle. The adaptor has a pair of switching circuits, each including a PNP transistor connected in series with an NPN transistor to chassis ground and each transistor connected to both stop and turn signal circuits of the towing vehicle and also to an NPN output transistor which is connected to an independent voltage source to drive the trailer signal lights independent of the voltage at the towing vehicle signal lights.
