LED Bulb Type H4 Pair – LG5017

The LG5017 H4 LED bulb pair is designed as a high-output lighting upgrade for vehicles using standard H4 headlamp fittings. With up to 380% more brightness than standard halogen bulbs, a crisp 6000 K cool white beam and simple plug-and-play installation, these LED bulbs help improve night-time visibility without major wiring changes.

Each bulb delivers approximately 1800 lm on low beam and 2500 lm on high beam, giving drivers a clearer view of roads, signs, hazards and work areas. The LG5017 is suitable for 9–16 V DC systems and is supplied as a pair for left and right headlamp replacement.

H4 LED Headlight Bulb Upgrade

The LG5017 is built for drivers who want a brighter, cleaner beam than standard halogen lighting. It is suitable for vehicles with H4 bulb fittings where the same bulb provides both low beam and high beam functions.

The 6000 K light colour gives a modern white output that improves visual contrast compared with older yellow halogen bulbs, helping reduce eye strain during night driving, early starts and poor weather conditions.

Strong Low Beam and High Beam Output

Each bulb produces approximately 1800 lumens on low beam and 2500 lumens on high beam, with a tolerance of ±10%. This provides useful forward visibility for unlit roads, rural routes, industrial sites, yards and service vehicles that operate in low-light conditions.

The improved brightness helps drivers identify obstacles, road markings and signs earlier, supporting safer and more confident driving.

Advanced Cooling and Thermal Control

The LG5017 uses a thermal design built around an aluminium shell, a pure copper thermal plate and a dual ball silent cooling fan. This helps move heat away from the LED chips and maintain stable light output during extended use.

An intelligent temperature control IC monitors heat and adjusts power when necessary, helping protect the LEDs from thermal stress and supporting longer service life.

Plug-and-Play Installation

These H4 LED bulbs are designed for straightforward replacement using the existing H4 connector. In many applications, installation requires no cutting, no extra relays and no complex wiring work.

The compact cooling design helps the bulbs fit into many standard headlamp housings, making them a practical upgrade for workshops, fleet maintenance teams and vehicle owners.
