450 mm steel-bodied rear lamp for heavy trucks and trailers
A full-size 450*175*36 mm combination lamp that carries stop, turn, reverse and tail functions in one stud-mounted housing, so a trailer builder wires one part instead of four. The 72-diode board is built for the rear face of heavy trucks and long trailers where the lamp sits low, takes road spray and still has to be read from a distance.
Truck and trailer OEM assembly lines, bodybuilders and aftermarket distributors who buy rear lighting by the pallet and need one lamp to cover all rear functions.
PC lens and housing, ultrasonically welded into one permanent waterproof body. Housing material and finish vary by model and are listed in the specification table.

Hardware production, laser marking, heat diffuser assembly, light source welding and thermal grease application run on our own semi-automatic lines. Lens installation, shell assembly, ring fixing and spring insertion follow in product assembly.
Boards are aged and photometrically checked in WEIKANG's own test room before the lens is welded, and every batch is inspected 100% before it leaves the factory.
Against the 44LED and 36LED plastic lamps in the same family, this is the largest and the only steel-bodied version — choose it where the rear panel is wide and the lamp has to survive knocks as well as water.
Confirm the rear panel cut-out and stud spacing against the 450*175*36 mm body
