The kit contains two H4 LED bulbs designed to provide high and low beam functionality. The supplied specifications list a variable power range of 85W–125W per bulb, giving 170W–250W per pair, along with a claimed brightness of up to 25,000LM.

With a 6500K white beam, integrated cooling fan, die-cast aluminium construction and H4 connector, the HJG Y6 is designed for compatible cars, SUVs, motorcycles and other vehicles using an H4 headlight holder.

Key Features

Y6 Projector Lens Design

The HJG Y6 uses a compact projector-style lens designed to concentrate the LED light source and provide a more controlled beam pattern.

High/Low Beam Function

The H4 configuration supports white high and low beam operation, making the bulb suitable for compatible headlight housings.

High Claimed Brightness

The supplied product specifications state up to 25,000LM brightness. Actual output may vary depending on vehicle voltage, installation conditions and measurement method.

CSP LED Chips

The bulb uses CSP LED technology, with the supplied description stating that the double-sided chip arrangement is designed to provide a compact light source and efficient illumination.

6500K White Light

The product is specified with a 6500K cool-white output, providing a modern white appearance for compatible headlight applications.

Integrated High-Speed Cooling

Each bulb includes an active cooling fan to help manage heat generated during operation. The supplied specifications mention a 12,000 RPM turbo fan.

Aluminium Heat-Dissipation Housing

The die-cast aluminium construction and radiator system are designed to transfer heat away from the LED assembly and support stable operation.

H4 Plug-and-Play Connection

The bulbs use an H4 connector and are designed for installation in compatible H4 headlight housings.

Important Specification Note

The supplied source contains different power references. The title describes the product as 250W, while the detailed specification states 85W–125W per bulb / 170W–250W per pair. It also states 25,000LM in the specification while another section mentions 10,000LM per light.

For accurate ecommerce publishing, the detailed specification above has been retained rather than presenting the conflicting figures as identical. Verify the final manufacturer-rated power and lumen output before publishing.

Focused Projector Beam

The HJG Y6 combines the H4 LED source with a compact projector lens designed to concentrate the light output.

The supplied product information states that the bulb base is laser-aligned during manufacturing to help achieve a consistent beam position.

For the best beam performance, the bulb should be correctly seated in the original H4 housing and properly aligned after installation.

Advanced Cooling System

The HJG Y6 is designed with multiple thermal-management components to help control heat generated by the LED system.

The cooling setup includes:

• High-speed cooling fan
• Aluminium radiator
• Die-cast aluminium body
• Heat-dissipation structure
• Aerodynamic ventilation
• Thermal-control design

The supplied information specifies a 12,000 RPM turbo fan designed to circulate air through the housing.

White 6500K High & Low Beam

The HJG Y6 provides a 6500K white light output with high and low beam functionality through its H4 configuration.

The cool-white colour temperature is designed to provide a modern appearance while delivering forward illumination for compatible headlight applications.

Beam performance will depend on the original headlight housing, bulb positioning and vehicle electrical system.

Low-Heat LED Design

Compared with conventional halogen-style lighting, the supplied product description highlights the bulb's active cooling and thermal-control system as key features for managing operating temperature.

The fan-assisted design helps move heat away from the LED assembly during operation.

Note: Actual operating temperature and service life depend on installation, electrical conditions, ventilation and usage.

Vehicle Compatibility

The HJG Y6 H4 LED bulbs are intended for vehicles using a compatible H4 headlight holder.

Potential applications include:

• Motorcycles
• Bikes
• Cars
• SUVs
• Compatible utility vehicles
• Other H4-equipped vehicles

Although the source describes the product as universal, actual fitment must be checked for each vehicle.

Before purchasing, confirm:

• Original bulb type is H4
• Connector matches
• Adequate rear clearance exists
• Cooling fan has sufficient ventilation
• Vehicle voltage is compatible

Installation Guide

1. Switch off the vehicle and allow the headlight assembly to cool.
2. Remove the existing H4 bulb.
3. Confirm the original socket and mounting base match H4 specifications.
4. Install the HJG Y6 bulb in the correct orientation.
5. Connect the H4 plug.
6. Make sure the cooling fan has enough clearance.
7. Reinstall the dust cover if the housing permits it.
8. Switch on the headlights and test high/low beam operation.
9. Check the beam pattern and adjust the headlight alignment before driving.

Professional installation is recommended, particularly for vehicles with limited headlight clearance or sensitive electrical systems.
