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.

La présente invention fait état d'une commande servant à actionner à la fois des feux de fonctionnement et des feux d'arrêt, ce qui permet d'adapter les feux d'arrêt et de clignotement combinés d'une remorque aux feux d'arrêt et aux clignotants indépendants d'un véhicule de remorquage. L'adaptateur est muni de deux circuits de commutation comprenant chacun un transistor PNP relié en série à un transistor NPN relié à la masse. Chaque transistor est connecté à la fois aux circuits des feux d'arrêt et des clignotants du véhicule de remorquage, ainsi qu'à un transistor NPN de sortie branché à une source de tension distincte alimentant les feux de signalisation de la remorque indépendamment de la source de tension alimentant les feux du véhicule de remorquage.
