47" (1200 mm) LED-Warnleuchte Bernstein Blinkend - LG639

47" (1200 mm) LED Warning Bar Amber Flashing – LG639

This 47" / 1200 mm LED amber warning light bar delivers high-output signalling for professional fleets that can’t afford to be ignored. With 29 selectable flash patterns, ECE R65 and ECE R10 approvals, and IP67 protection, it’s engineered for road-legal, all-weather use on modern 12 V and 24 V systems. Ideal on trucks, tractors, construction machinery and utility vehicles where reliable, high-visibility warning is a safety-critical tool, not a nice-to-have.

When you’re working roadside or in a field at dusk, you need an amber warning bar that cuts through rain, spray, dust and headlights. The LG639 uses high-class LED diodes behind an efficient TIR lens system to push out a clean, punchy signal pattern, clearly visible in daylight and night conditions. At 128 W total power, it’s a serious light output with tightly controlled optics, not just raw wattage.

The bar runs on 9–32 V DC, so it’s fully at home on mixed fleets with both 12 V and 24 V vehicles. An in-cab control unit is included, giving the driver quick access to all 29 flash patterns as well as control of the white side position light option where fitted. So you can standardise one bar across multiple platforms – trucks, trailers, agricultural equipment and construction vehicles – and keep control of warning behaviour from the cab.

Built for harsh environments, the LG639 carries an IP67 ingress protection rating, which means it’s dust-tight and protected against temporary immersion. In practice, it shrugs off rain, washdowns and muddy site conditions. ECE R65 approved light output gives you proven on-road warning performance, while ECE R10 and EMC – CISPR25 Class 3 approvals help ensure the bar won’t interfere with radios, GPS, or other vehicle electronics. At 1230 × 150 × 75 mm (L × W × H), it gives full 1200 mm coverage with a low profile that sits neatly on cabs and roof racks.

Installation is straightforward for any competent auto electrician or workshop. Standard 9–32 V wiring, a dedicated in-cab controller included in the kit, and a universal design mean it’s well suited to both OEM fit and retrofit onto existing fleets. Once installed, the solid-state LED design offers a long service life with minimal maintenance compared to older halogen or rotating beacons.

• ECE R65 approved – road-legal amber warning performance where R65 is required by local regulations.
• ECE R10 approved & EMC – CISPR25 Class 3 – designed to limit electrical interference with vehicle CANbus, communications equipment and sensitive electronics.
• In-cab control unit included – supplied as a complete kit, simplifying installation and giving the driver direct pattern and mode control.

Ideal Applications

• Highway maintenance and service trucks operating on live carriageways and hard shoulders.
• Agricultural tractors, harvesters and slurry tankers working on-road and in-field, often in low-light seasons.
• Construction and quarry vehicles, including tippers, sweepers, rollers and site support vehicles.
• Utility and council fleets – road inspectors, powerline crews, water and telecoms service vehicles.
• Recovery, breakdown and escort vehicles needing compliant, highly visible amber warning on public roads.
