LED Tail Light Rectangular Combination with Triangle & Built-In Smart Resistor (LH) - LG574

LED Tail Light Rectangular Combination with Triangle & Built-In Smart Resistor (LH) – LG574

This LED rectangular combination tail light with triangle is built for professional trailers and plant fleets that can’t afford lighting failures. The LG574 left-hand lamp combines stop, tail, indicator, fog, reverse, reflector and red triangle in one compact, road-legal unit for 12 V and 24 V systems (9–33 V DC). Fully ECE approved and CISPR 25 Class 4 compliant, it delivers strong, stable light output without upsetting sensitive vehicle electronics.

If you run modern trailers with complex electrics, you’ll know the pain: dash errors, fast-flash indicators, or weak aftermarket lamps that die under vibration. The LG574 solves that cleanly. It uses high-intensity CREE XTE LEDs with a service life of 50,000 hours, sealed to IP67 for dependable performance in year-round European weather, haulage yards and agricultural work.

This left-hand LED tail light packs seven functions into a footprint of 256 × 130 × 40.5 mm, including the mandatory rear red triangle reflector for trailers. You get stop, tail, indicator, fog, reverse and reflector, plus the triangle, in a single robust housing. Light output is crisp and controlled: amber indicators, deep red stop/tail, and a 6000 K white reverse beam that gives clear visibility when backing into tight yards or unlit loading bays.

Electronics are fully engineered for modern vehicles. The wide 9–33 V DC input covers both 12 V and 24 V systems, while EMC to CISPR 25 Class 4 and ECE R10 approval mean radio, GPS and telematics stay clean. A built‑in smart resistor on the indicator circuit helps prevent bulb‑failure warnings and hyper‑flash on many CANbus-equipped tractors, trucks and towing vehicles, without extra load resistors or messy add‑ons.

Installation is straightforward. The LG574 comes pre‑wired with plug & socket and 60 cm of cable, so your auto electrician can swap out older lamps with minimal downtime. With approvals including ECE R3, R6, R7, R23, R38 and R91, the lamp is engineered to meet European road requirements when correctly installed on compliant vehicles and trailers. Vibration-tested to 15 G, it’s designed to stay in place and stay lit on rough roads, fields and construction sites.

Key Features

• 7‑function LED combination lamp (Left Hand) – Stop, Tail, Indicator, Fog, Reverse, Reflector and Red Triangle in one unit, reducing wiring and mounting points.
• Wide voltage range: 9–33 V DC – suitable for both 12 V and 24 V commercial vehicles, trailers and agricultural machinery.
• High-intensity CREE XTE LEDs – proven LED platform with 50,000 h service life for long-term reliability and low maintenance.
• Integrated red triangle reflector (R3 / R91 approved) – meets trailer rear identification requirements when fitted in the correct position.
• Built‑in smart resistor on indicators – helps avoid CANbus bulb error warnings and fast-flash on many modern towing vehicles, without additional load resistors.
• Certified ingress protection: IP67 – fully sealed against dust and temporary immersion, ideal for wash-downs, winter roads and agricultural use.
• Extensive ECE approvals – ECE R10 (EMC), R3, R6 (indicator), R7 (tail/stop), R23 (reverse), R38 (fog), R91 for road‑legal use on approved vehicles and trailers.
• EMC safety: CISPR 25 Class 4 – reduced radio frequency interference, protecting radios, GPS, CB, and telematics systems from noise.
• Compact, robust housing – 256 mm (width) × 130 mm (height) × 40.5 mm (thickness), vibration-tested to 15 G for heavy-duty operation.
• Ready-to-fit connection – supplied with plug & socket and 60 cm cable, making replacement and upgrades faster and cleaner for installers.

Ideal Applications

• Commercial trailers and semi‑trailers – curtain-siders, flats, low-loaders and box trailers running long hours in mixed weather.
• Agricultural trailers and implements – grain trailers, slurry tankers, bale and livestock trailers needing rugged, sealed rear lighting.
• Plant and construction equipment – site trailers, generators, towable compressors and machinery transporters used on and off road.
• Recovery and specialist vehicles – car transporters, tilt-beds and support trailers that require reliable, multi-function EU-compliant lighting.
• Fleet upgrades and refits – operators standardising on 9–33 V LED rear lights for reduced downtime and lower maintenance costs.
