A warning and scene-lighting package on EVB's unit 406, a Kenworth T880 carrying a 50-ton heavy wrecker body. Everything about this one is bigger: the truck works highway recoveries where it holds a lane for hours, and the crew has to see what they're rigging in the dark, so the build is as much about scene light as it is about warning.
The main bar sits up on a stainless light tower behind the cab, clearing both stacks and the boom so nothing blocks it and it reads over the top of stopped traffic — amber and white across the full width. Square LED work lamps hang off the tower legs aimed down onto the deck and the winches, with more amber at the cab roof and markers and warning worked down the body. Every run had to be routed around a hydraulic body and a boom that moves, so the wiring was planned around the pivot points rather than pulled straight and hoped for.
