Upgrade to 'Plug and Play' Trailer Lamps
The Model 35 range introduces a complete 'Plug and Play' solution for box trailer lighting, making installation easier and quicker. Perfect for DIY. Narva's 'Plug and Play' waterproof connection system utilises over moulded connectors that quickly join the lamps and trailer plug to the main wiring harness. No splicing or joining of wires is required, making connections a tool free operation.
Designed from the ground up, the Model 37 trailer lamp has been engineered for use on boat trailers where regular submersion is common (suitable for boat trailers up to 7m). The lamps are protected from water ingress with a two-stage sealing system that incorporates ultrasonic welding and a two-part epoxy glue. This allows the lamps to comply with the stringent IP68 standard. Each lamp is fitted with a waterproof connector and joins effortlessly to the main harness which is also compliant to the IP68 standard. All hardware is made from 316 stainless steel and suitable for marine environments.
