HJG N18 50W Laser Focus H4 LED Projector Bulb

Upgrade your vehicle's factory lighting with the HJG N18 Laser Focus H4 LED Projector Bulb, a compact lighting solution designed for motorcycles, scooters and cars with compatible H4 headlight housings. Rated at 50W, this projector bulb combines focused illumination, multiple lighting functions and active cooling in one practical design.

The HJG N18 provides a white low beam, a white + yellow hyper-focus laser high beam, and a distinctive Red Devil DRL mode. Its integrated mini projector lens is designed to concentrate light into a controlled beam pattern, while the built-in cooling fan helps manage heat generated during operation.

With an H4 socket and direct-replacement design, the HJG N18 is suitable for compatible vehicles where the original headlight uses an H4 bulb connection.

Key Features & Benefits

50W LED Projector Bulb
The HJG N18 uses a 50W LED lighting system to provide a significant lighting upgrade for compatible H4 headlight applications.

White Low Beam
The low-beam mode produces a crisp white output designed for everyday nighttime riding and driving.

White + Yellow Hyper Focus High Beam
The high-beam configuration combines white illumination with a yellow laser-style hyper-focus output. The yellow component is particularly useful in conditions such as rain, fog and dust where contrast can become more challenging.

Red Devil DRL Mode
The Red Devil DRL provides a distinctive red accent during daytime operation, giving the headlight a customized appearance.

Built-In Cooling Fan
A high-speed cooling fan is integrated into the bulb assembly to assist with heat management during operation.

Mini Projector Lens
The integrated projector optics are designed to focus the LED output rather than allowing uncontrolled light dispersion inside the headlight housing.

H4 Socket Compatibility
The bulb uses an H4 socket, making it suitable as a replacement option for compatible motorcycles, scooters and cars using an H4 headlight setup.

Three Lighting Functions

The HJG N18 combines three distinct lighting configurations:

1. White Low Beam

The white low beam is designed for regular nighttime use, providing forward-facing illumination for roads, signs and surrounding obstacles.

2. White + Yellow Hyper Focus High Beam

The high-beam mode combines white and yellow output to create a distinctive long-range lighting effect. The yellow component can be useful in wet, dusty or foggy environments where excessive white-light reflection may reduce visual contrast.

3. Red Devil DRL

The Red Devil DRL mode adds a bold visual accent to the headlight assembly and provides a distinctive appearance during daytime use.

Precision Projector Beam

Unlike conventional LED replacement bulbs that can scatter light within a reflector housing, the HJG N18 incorporates a mini projector lens intended to concentrate the light output into a more defined pattern.

The projector design is intended to provide a sharper distribution of light, while correct installation and headlight alignment remain essential for responsible road use and minimizing unwanted glare.

Cooling & Heat Management

High-output LED lighting generates heat, making thermal management an important part of the bulb design.

The HJG N18 includes:

• Integrated high-speed cooling fan
• Heat-dissipating bulb housing
• Active airflow around the LED assembly
• Compact projector construction
• Thermal management designed for continuous operation

Keep the cooling area unobstructed after installation to allow proper airflow.

Plug-and-Play H4 Installation

The H4 socket configuration makes the HJG N18 suitable for compatible direct-replacement applications. The compact bulb design is intended to fit inside compatible headlight housings without requiring a separate projector assembly.

Before purchasing, check the original bulb type, available rear clearance and electrical configuration of your vehicle.

Technical Specifications

Vehicle Compatibility

The HJG N18 is designed for vehicles that use an H4 headlight socket, including compatible:

• Motorcycles
• Scooters
• Cars
• Other H4-equipped vehicles

Compatibility is dependent on the vehicle's headlight housing, bulb dimensions, connector configuration and available rear clearance. Always verify these details before installation.

Installation Notes

1. Turn off the vehicle and allow the original headlight to cool.
2. Remove the existing H4 bulb following the vehicle manufacturer's procedure.
3. Compare the original bulb connection with the HJG N18 H4 socket.
4. Install the HJG N18 securely into the compatible headlight housing.
5. Connect the H4 wiring correctly.
6. Ensure the cooling fan and rear portion of the bulb have sufficient clearance.
7. Test the low beam, high beam and DRL functions.
8. Adjust the headlight beam correctly before nighttime driving.

Professional installation is recommended if the vehicle requires wiring changes or if the bulb does not fit the original housing without modification.

Maintenance & Care

• Keep the projector lens clean and free from dust.
• Do not block the cooling fan or airflow area.
• Check the electrical connector periodically.
• Inspect wiring for loose connections.
• Ensure the bulb remains firmly secured inside the housing.
• Recheck beam alignment if the headlight assembly is removed or adjusted.
