The OCAM Extendable Towing Mirrors are designed for towing trailers, boats, caravans and horse floats. They are available in black and chrome, with or without indicators. The large flat mirror is electric (for most makes and models) and operated using the vehicle’s factory controls. The small lower mirror, operated manually, is convex and provides a wider angle view. The mirrors exend manually on a solid extension slide.  They are easy to fit - remove the door card, replace the factory mirror with the new towing mirror, and plug and play.  The OCAM towing mirrors will increase your range by approximately 200mm over standard factory mirrors.
