LED Tail Light Triangular Combination with Built In Smart Resistor RH – LG571

The LG571 LED triangular combination tail light is a right-hand rear lamp designed for trailers, low loaders, plant equipment, agricultural machinery, commercial vehicles and fleet bodies. It combines stop, tail, indicator, fog, reverse, reflector and rear warning triangle functions in one compact triangular unit.

With 9–33 V DC operation, built-in smart load resistance, 45 Cree XTE LEDs, IP67 protection, ECE approvals and CISPR 25 Class 4 EMC performance, the LG571 is built for modern 12 V and 24 V vehicle systems that need reliable, road-ready rear lighting.

Right-Hand Triangular Combination Tail Light

The LG571 is designed for the right-hand rear side of trailers and commercial vehicles. It combines multiple rear lighting functions in one triangular housing, helping reduce the need for separate lamps, extra reflectors and additional wiring.

Its compact 218 × 145 × 35 mm body gives a clean rear installation while still providing full visibility for stop, tail, indicator, fog, reverse, reflector and triangular warning functions.

Built-In Smart Resistor for Indicators

The LG571 includes a built-in smart load resistor for the indicator function. This helps prevent hyperflash and bulb-out warnings that can happen when standard LED lamps are fitted to modern trucks, trailers and CANbus-style vehicle systems.

Because the resistor is already integrated, installers do not need to add external resistors, extra relays or complicated wiring modifications in many applications.

45 Cree XTE LEDs for Strong Rear Visibility

The lamp uses 45 high-intensity Cree XTE LEDs to deliver clear amber, red and white rear lighting. The reverse function provides a crisp 6000 K white output, helping improve rear visibility during coupling, reversing, yard manoeuvring and night-time work.

The LED design offers low current draw, long service life and stable output compared with traditional filament lamps.

Suitable for 12 V and 24 V Systems

The wide 9–33 V DC input range makes the LG571 suitable for both 12 V and 24 V electrical systems. This is ideal for mixed fleets using trailers, trucks, agricultural machinery, low loaders and commercial vehicle bodies across different voltage platforms.

It helps fleet operators and workshops standardise rear lighting across a wide range of vehicles and equipment.

IP67 Protection and 15 G Vibration Tested

The LG571 is rated IP67, helping protect the unit against dust, rain, road spray, mud and temporary water exposure. It is built for trailers and machinery that regularly face wash-downs, rough roads and harsh outdoor environments.

The lamp is also vibration tested to 15 g, making it suitable for agricultural trailers, plant transporters, low loaders and heavy-duty commercial use.

ECE Approved and EMC Safe

The LG571 is approved to ECE R10, R3, R6, R7, R23, R38 and R91. These approvals cover electromagnetic compatibility, reflectors, indicators, stop and tail functions, reverse, rear fog and triangular warning requirements.

CISPR 25 Class 4 EMC performance helps reduce interference with radios, GPS, telematics, communication systems and onboard electronics.

Simple Installation

The lamp is supplied with a socket and 30 cm cable, giving installers enough length to connect into existing harnesses, junction boxes or trailer wiring systems.
