Abstract: A light mount and associated control cable support devices, adapted for insertion into body gaps of a vehicle being towed. Soft pliable construction of insertion wedge portions assure no damage to the surface finish of the vehicle being towed. Control cable mounting wedges of the same material prevent chafing of the surface by the control cable. The signal light unit has a bulb cover allowing the light to be seen from top, bottom, both sides and front, so that the light may be mounted in any available body gap while remaining visible from the rear of the towed vehicle.
