Peace be upon you. Trailer hitch parts are available, from lighting and sockets to internationally approved systems by manufacturers and developers of these systems. Of course, there are several types of sockets in the local markets, but some types are not approved. The type of car for which the trailer hitch system is to be installed determines the appropriate type for the car according to the person's need and the type of car to determine the appropriate type. When ordering trailer hitch electrical parts, they can be sent to the buyer's address at their own expense, and all attached wires and parts will be identified for ease of installation and connection. A video clip of the system testing process will also be attached before sending it to anyone outside my country. It is also possible, if agreed with the buyer, to install it by me. Sorry for not attaching prices, they vary according to the agreement and need. Location: Bahrain. For communication and inquiries: 0097333202885
