Avoiding Lighthead Corrosion with the XTP Product Line

Metal vs. polycarbonate housing: Code 3's product design enhances durability and reliability

The “double-sealing” features combined with polycarbonate housing make the XTP Series extremely resistant to damage and failures caused by water ingress and corrosion.

The manufacturing process includes ultrasonic welding, which is an automated and efficient way to join molded parts. The ultrasonic welding produces friction from acoustic energy that creates heat and joins the two parts together on a molecular level. It produces a high-quality bond and a clean, precise seal. It does not require filler material nor excessive heat, so there is no potential for contamination. Additionally, the XTP directional lights include a gasket that adds extra protection against water intrusion. Combined with the ultrasonic welding, the gasket provides the lighthead double-sealed protection.

As opposed to metal housing, the XTPs are made of a resistant polycarbonate material that prevents lighthead damage from salt, calcium chloride and cleaning agents such as trisodium phosphate (TSP). The products can be used on virtually any vehicle surface and it is especially recommended for bumpers and push-bumpers. In those areas, the coating on a lighthead with metal housing can be cracked due to impacts, rocks or other environmental elements. This creates conditions for potential water ingress and corrosion.

The double-sealing capability and the polycarbonate housing make the XTPs excellent alternatives for the bumper and push-bumper applications of any vehicle.
