Some tow vehicle electrical systems may not be fully compatible with the LED road lights fitted to modern trailers and caravans, including the new range from Swift. In cases where problems are identified, an electronic control unit (VLM4) can be ordered direct from Sargent Electrical Services Limited for installation in the caravan. This unit simply plugs in-line with the 13 pin car connection cable at the rear of the caravan towing fuse box.

Following continuing vehicle testing, we are producing two versions of the VLM4. VLM4-A for the majority of vehicle systems and VLM4-B for some later BMW models. Please ensure that you provide clear vehicle details below we will then select and send the appropriate unit. Due to the complexity of some vehicle systems we cannot guarantee that the VLM4 will work with all manufacturers OEM or after-market towing electrics solutions.
This part is currently only available for installation in Swift Caravans.
