The Trailer Vision 50A Blue Cover Assembly is a purpose-built surface-mount housing designed to neatly and securely accommodate a standard 50A Anderson-style SB50 plug on caravans, trailers, camper trailers, and 4WD tow vehicles. Colour-coded blue for instant identification of auxiliary or secondary power circuits, the assembly snaps the plug firmly into a UV-stabilised polypropylene housing that mounts flush against any flat surface — bullbar, chassis rail, or A-frame — using a simple two-screw fixing pattern. The robust cover flips open for connection and closes to shield the plug contacts from dust, moisture, and road grime when not in use, protecting your 12V system against the harsh Australian outback environment.

This cover assembly is the go-to solution for Australian caravanners and off-road enthusiasts who want a clean, professional-looking 12V connection point that holds up on corrugated dirt tracks and long-haul touring routes. It suits anyone running a secondary battery system, solar input, or DC-to-DC charger between tow vehicle and caravan, camper trailer, or RV — keeping your Anderson plug safe and accessible at all times. The blue colour coding makes it easy to distinguish auxiliary charging circuits from standard power connections at a glance, reducing wiring errors during hitching and unhitching in low-light conditions at camp.
