The HTS Spares HEL3399 is a 600mm LED beacon light bar designed for professional use on plant machinery, tool hire fleets, and construction vehicles operating on UK roads and work sites. Powered by 56 individual 3-watt LEDs across its 600mm width, it delivers the consistent high-intensity amber warning output demanded by fleet operators, site managers, and hire companies alike. Chapter 8 of the Traffic Signs Manual - the UK's key guidance for traffic safety measures at roadworks and temporary situations - recommends that work vehicles are equipped with a roof-mounted, flashing, amber warning light bar made up of at least two independent light sources, and recommends the use of ECE R65 approved products. The HEL3399 meets both requirements, making it a dependable choice for compliance-conscious operators across the plant hire and construction sectors.
Built for the realities of UK construction and hire environments, the this light bar carries an IP67 ingress protection rating. IP67 ensures total dust exclusion and the ability to withstand temporary immersion in water - critical on active construction sites where equipment is routinely exposed to rain, standing water, mud, and pressure washing. ECE R65 certification ensures that warning lights meet specific performance criteria for brightness, colour, and visibility distance, so lights can be seen clearly in various environmental conditions. Complementing this, ECE R10 approval focuses on protecting road users from electromagnetic interference emitted by the light, ensuring that electronic systems on the host vehicle function correctly without disruption. Together, these approvals give fleet managers and plant hire operators confidence that the HEL3399 performs to the highest available standards - in the workshop, on the highway, and on site.
