Build Your Truck in 3D with RealTruck Builder
Form Lighting LED sidemarkers give dually trucks a modern, upgraded appearance with smoked lenses and full-length LED strips. The set includes four lamps and delivers brighter illumination than the factory sidemarkers.
Built for durability and reliable performance, the lamps feature UV-coated polycarbonate lenses, automotive-grade LED emitters, breather vents, factory-style plug-and-play connectors and integrated transient protection to help safeguard the electronics.
Installation is straightforward, using the factory mounting points and connectors for a true plug-and-play replacement. Simply replace the factory housings without additional wiring. The lamps are engineered for a precise fit, helping eliminate body gaps, warning errors and LED flickering.
Backed by a two-year warranty and US-based customer support.
Installation takes approximately 10-20 minutes, with no drilling or vehicle modification required
