LED bakljus kombination lastbil/släp med inbyggd smart resistor (vänster) - LG552

LED Tail Light Combination Truck/Trailer with Built-In Smart Resistor (LH) – LG552

This 24 V LED combination tail light for trucks and trailers is built for fleets that can’t afford lighting failures or CANbus headaches. The LG552 left-hand lamp combines stop, tail, indicator, fog, reverse and reflector in one robust, road-legal unit with integrated number plate and side marker lighting. Fully E-marked and ECE approved, with IP68 protection and CISPR 25 Class 4 EMC, it’s engineered for long-haul work in real European conditions.

The LG552 solves a common problem on modern 24 V trucks and trailers: LED upgrades that trigger bulb failure warnings or flash too fast. This lamp includes a built-in smart load resistor on the indicators, so it behaves correctly on most OEM systems without extra resistors or relay swaps. One lamp. Clean install. No guesswork.

Designed as a left-hand side (LH) LED rear combination light, it covers all core rear functions: stop / tail / indicator / rear fog / reverse / reflector, plus an integrated bottom number plate light and side marker light. That means fewer separate lamps to mount, wire, and maintain. High-intensity CREE XTE LEDs deliver strong, crisp output in amber, red and white, with a 6000 K reverse light for clear visibility when manoeuvring in yards or depots.

This unit is IP68 rated, so it’s sealed against dust and resistant to long-term immersion – ideal for vehicles working in constant spray, winter road salt and regular wash cycles. It’s vibration tested to 15 G, so it stays together on rough roads and construction routes. With a 50,000 h rated lifespan, it’s built for years of service, not seasons.

Installation is straightforward. The LG552 runs on 24 V DC and is supplied with a 7-pin plug and 100 cm cable, plus a built-in side connection plug to simplify trailer wiring looms. E-mark approvals (ECE R3, R4, R6, R7, R23, R38, R91) confirm it’s road-legal across Europe when installed correctly, and ECE R10 / CISPR 25 Class 4 mean it’s been tested for low radio interference, protecting sensitive vehicle electronics and communications.

Key Features

• Complete LH rear combination lamp – stop, tail, indicator, fog, reverse and reflector in one compact housing for clean, simple rear lighting layouts.
• Built-in smart load resistor on indicators – helps prevent CANbus bulb errors and incorrect flash rates on modern 24 V trucks and trailers.
• Integrated number plate and side marker lights – bottom number plate light and side marker lamp built in, reducing separate fixtures and wiring points.
• High-intensity CREE XTE LEDs – proven LED platform delivering bright amber/red/white output with a 6000 K reverse beam for clear backing visibility.
• 24 V DC operation – designed specifically for heavy trucks, trailers and semi-trailers on European 24 V electrical systems.
• Long-life design – 50,000 h rated lifespan – reduces downtime, lamp changes and workshop call-backs across demanding fleets.
• IP68 ingress protection – fully sealed against dust and resistant to prolonged water exposure, ideal for frequent washing and harsh weather.
• Vibration tested to 15 G – suited to tippers, low-loaders, plant trailers and rough-road logistics without premature failures.
• ECE approved and road-legal – E-mark and ECE R3, R4, R6, R7, R23, R38, R91 approvals for reflectors, indicators, stop/tail, reverse and fog functions.
• Low EMC emissions – ECE R10 and CISPR 25 Class 4 compliance for radio frequency suppression, protecting radios, telemetry and OE electronics.
• Ready-to-fit wiring – supplied with 7-pin plug and 100 cm cable, plus side connection plug to simplify trailer loom integration.
• Practical dimensions – approximately 486 mm (W) x 130 mm (H) x 70 mm (T) for easy retrofit on most European truck and trailer rear bars.

Ideal Applications

• 24 V articulated trucks and semi-trailers needing reliable LED rear combination lights with integrated smart resistor.
• Heavy haulage, low-loaders and machinery transporters working in high-vibration, long-distance operations.
• Tipper trucks, grab lorries and construction trailers exposed to mud, dust, spray and frequent pressure washing.
• Municipal and utility fleets (refuse trucks, maintenance trailers, service units) requiring ECE-approved, low-EMC lighting.
• Agricultural and forestry trailers using 24 V systems where robust, sealed LED lighting is essential.

Why Choose LED-Global Lighting

LED-Global focuses on high-performance vehicle lighting for professional users across Europe. Every lamp is selected and engineered with an eye for the real world: voltage stability, EMC behaviour, sealing, and how it copes on a wet January night on the N-road. Products like the LG552 combine European approvals, proven LED technology and robust construction, so you spend less time chasing lighting faults and more time keeping vehicles working. That’s the standard we design to – and the reason our lighting is trusted by fleets, fitters and bodybuilders across the region.
