The now-iconic duraled range revolutionised the safety of the New Zealand and Australian transport fleets. First conceived and field trialled by hella New Zealand in 1998, our radical pursuit to create a range of fit and forget, highly visible led marker and signal lamps, permanently lowered the cost of ownership for our fleets and made our roads safer.


fit & forget by design is a hella no-compromise philosophy and commitment to design for long-term durability and safety. Products that carry the duraled? name will outlast the life of the vehicle. Whilst keeping its design heritage and appearance the duraled range has been continuously upgraded to the latest material and electronic component technology.

a complete fit & forget solution for trailers or caravans.
lamps are completely sealed, maintenance-free. Designed to withstand high-pressure washing and temporary submersion.
