Key Features

Dual Projector Lens Design

The RTD Lens system uses a compact projector-style optical design to help concentrate the LED output and provide a more focused illumination pattern.

White Hi/Lo Beam

The bulbs provide white high and low beam lighting, making them suitable for compatible H4 headlight applications.

Red Devil DRL Effect

The integrated Red Devil DRL adds a distinctive styling element to the headlight while providing an additional daytime-lighting effect.

100W LED Headlight Set

The supplied technical specification lists 100W total power for the two-piece set.

Up to 10,000LM Claimed Brightness

The product specifications state 10,000 lumens. The source also contains references to 12,000LM in the original title, so the final published brightness should be verified against the manufacturer's current specification.

CSP LED Technology

The bulbs use CSP LED chips designed to provide a compact light source with high luminous efficiency and concentrated illumination.

Integrated Cooling Fan

Each bulb incorporates an active cooling fan to help remove heat from the LED assembly during operation. The supplied information specifies a turbo fan speed of up to 12,000 RPM.

Aluminium Heat-Dissipation System

The die-cast aluminium construction and thermal-management components are designed to help dissipate heat and maintain consistent operation.

H4 Plug-and-Play Connection

The bulbs use an H4 connector and are intended for compatible H4 headlight housings, making installation simpler where the vehicle's original socket matches.

Technical Specifications

Specification note: The supplied source has inconsistent power and brightness references, including 75W/100W and 10,000LM/12,000LM. The technical section above follows the detailed specification stating 100W and 10,000LM. Verify the manufacturer's final specifications before publishing.

Focused Projector Beam

The RTD Lens projector structure is designed to concentrate the LED light source into a more controlled beam. The supplied product information states that the bulbs are laser-aligned during manufacturing to help achieve consistent positioning.

Correct installation and beam adjustment remain important because the final beam pattern depends on the vehicle's original headlight housing, reflector/projector design and bulb positioning.

Advanced Cooling System

High-output LED bulbs require effective thermal management. The HJG RTD Lens bulbs combine several cooling elements, including:

• Integrated high-speed cooling fan
• Die-cast aluminium housing
• Aluminium heat radiator
• Thermal-control design
• Aerodynamic ventilation
• Compact heat-dissipation structure

The supplied specification mentions a 12,000 RPM turbo cooling fan designed to circulate air through the housing and help manage operating temperature.

White High & Low Beam

The HJG RTD Lens H4 bulbs are designed to provide a white high beam and white low beam.

The supplied specifications list a 6500K white colour temperature, giving the headlight a cool-white appearance suitable for compatible night-driving applications.

The actual beam performance will depend on the vehicle's original headlight housing and correct bulb orientation.

Red Devil DRL

The integrated Red Devil DRL gives the headlight a distinctive appearance when the DRL function is used.

This feature is primarily intended as a styling/daytime-running-light element. Always follow applicable local regulations regarding coloured lighting and DRL usage on public roads.

Vehicle Compatibility

The HJG RTD Lens H4 bulbs are intended for vehicles equipped with a compatible H4 headlight socket.

Potential applications include:

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

The source describes the product as universal, but H4 compatibility should always be confirmed before ordering.

Important: A vehicle model being listed as compatible does not guarantee fitment. Check the original bulb type, socket, available rear clearance and electrical system before purchase.

Installation Guide

1. Switch off the vehicle and allow the original headlight to cool.
2. Remove the existing H4 bulb.
3. Confirm that the original connector and mounting base match H4 specifications.
4. Install the HJG RTD Lens bulb in the correct orientation.
5. Connect the H4 connector.
6. Make sure the cooling fan has sufficient ventilation and clearance.
7. Secure the bulb and reinstall the dust cover where applicable.
8. Turn on the headlight and test high/low beam operation.
9. Check and adjust the beam alignment before driving.

Professional installation is recommended, especially for vehicles with limited headlight clearance or sensitive electronic systems.
