WEIKANG manufactures stop, turn, tail, reverse, marker and cab roof lamps for truck and trailer builders, fleets and distributors. Every lamp is ultrasonically welded into one sealed IP67 body and tested before it leaves our Hefei factory.
Five categories organised around the hole in the panel, not around marketing families: 4 inch round, 6 inch oval, full-size combination lamps, side markers and cab roof lamps.

Hardware production, assembly, welding, aging and photometric testing all happen in WEIKANG's own facility. These are the real workshops your lamps come from.

Hardware production runs in the company's own SMT workshop, where boards are placed and reflowed before assembly.

Lens and housing are ultrasonically welded into one permanent waterproof body — the step that gives the range its IP67 rating.

Product assembly: lens installation, lamp shell assembly, inner and outer ring fixing and spring insertion.
Four programs covering rear lighting, side marking, warning behaviour and private label supply, each mapped from requirement review to shipment.

What multi-voltage really means on a spec sheet and when one part number can cover both 12V and 24V fleets.
