• Simple wiring: Color-coded leads make installation straightforward: white negative, red positive for high brightness and black positive for low brightness.

Who It's For

The lights are best for trailer owners, caravan and camper owners, small truck and ATV operators who need reliable 12V tail, indicator or reverse lighting with a clean chrome finish. They suit DIY installers and small fleets that want consistent brightness and weather resistance at a modest cost.
