Ampoule LED Type H4 (Paquet) - LG5017

H4 LED Headlight Bulb (Pair) – LG5017

This is a direct, high-performance upgrade for any vehicle using standard H4 halogen bulbs. Our LG5017 H4 LED bulb pair delivers a massive increase in brightness, engineered into a simple plug-and-play design for a quick, effective replacement. It’s built to last, thanks to a sophisticated thermal management system that ensures consistent performance, shift after shift.

Upgrading your vehicle’s headlights from halogen shouldn't be a compromise. That’s why we engineered the LG5017. It’s not just about making them brighter—though with a 380% increase in light output over standard bulbs, the difference is night and day. It’s about creating a better, safer beam. The crisp, 6000 K daylight-white colour reduces eye strain on long journeys and makes it easier to spot hazards on the road ahead. With a powerful 1800 lumens on low beam and a formidable 2500 lumens on high beam, you get superior visibility where you need it most.

Heat is the enemy of any high-performance LED. It kills brightness and shortens lifespan. So, we've built a robust thermal management system to keep the LG5017 running cool and reliably. Heat is drawn from the chip via a pure copper plate—with thermal conductivity 60 times higher than ordinary aluminium—and transferred through a copper PCB. From there, an aluminium shell provides a large surface for heat dissipation, while a built-in, dual ball silent fan provides active and efficient cooling. It’s a complete system.

To protect this system, an intelligent temperature control IC constantly monitors the bulb’s working temperature and automatically adjusts power output to maintain optimal performance without overheating. This ensures a long, dependable service life. Installation is a straight swap for your old H4 bulbs. No cutting wires, no complex modifications. It’s a true Plug and Play design, built for 12 V vehicles and supplied as a matched pair for a perfectly balanced beam pattern.

Key Features

• Dramatic Brightness Increase: Engineered to be up to 380% brighter than standard H4 halogen bulbs.
• Dual Beam Functionality: Provides both a powerful low beam (1800 lm) and a long-reaching high beam (2500 lm) in a single unit.
• Crisp 6000 K Colour Temperature: A modern, daylight-white light that reduces driver fatigue and improves hazard perception.
• Advanced Thermal Management: A multi-stage system featuring a pure copper plate, copper PCB, and a dual-ball silent fan for superior heat dissipation and longevity.
• Intelligent Power Control: An integrated IC system actively manages power based on temperature, ensuring stable output and protecting the bulb from overheating.
• Plug and Play Installation: Designed as a direct, no-fuss replacement for standard H4 bulbs.
• Efficient Performance: Consumes less power (22 W low / 32 W high) than halogen bulbs, reducing the load on your vehicle’s alternator and electrical system.
• Engineered for 12 V Systems: Operates on a stable 9–16 V DC input, perfect for cars, vans, tractors, and light commercial vehicles.
• Supplied as a Pair: Ensures a perfectly matched and balanced beam pattern for safe, consistent road illumination.

Ideal Applications

• Trucks, HGVs, and commercial vans (12 V systems)
• Agricultural tractors and machinery (12 V systems)
• 4x4s and off-road vehicles requiring a road-legal H4 upgrade
• Cars and light commercial vehicles using H4 halogen bulbs
