PROJECTOR LENS DESIGN

The integrated projector lens helps concentrate the LED output for more controlled road illumination.

This provides improved forward visibility compared with worn or dim standard lighting while helping reduce unnecessary scattered light when correctly installed and aligned.

HIGH & LOW BEAM

The H4 3-pin design combines high and low beam functionality within the same bulb.

This makes it suitable for compatible vehicles where a single H4 bulb operates both headlight beam functions.

SMART DRIVER MODULE

An intelligent electronic driver helps regulate power delivery to the LED system for stable operation.

This works together with the cooling system to support consistent lighting performance.

COOLING SYSTEM

A built-in high-speed cooling fan and aluminium housing help transfer heat away from the LED components.

Adequate ventilation and sufficient space behind the headlight housing are required for correct installation.

IMPORTANT FITMENT WARNING

The vehicle list above is a general compatibility guide and does NOT guarantee fitment.

The same vehicle model can use different headlight bulbs depending on:

• Model year
• Trim level
• Headlight housing
• Factory lighting specification
• High/low beam configuration
• Vehicle market specification

Always check your existing bulb before ordering.

Your vehicle must use an H4 3-pin bulb with combined high and low beam functionality.

Do not purchase based only on vehicle make and model.

SIZE & CLEARANCE NOTICE

LED projector bulbs can require more installation space than standard halogen bulbs due to the projector assembly, cooling fan and electronic components.

Before ordering, check that your headlight housing has sufficient:

• Rear installation depth
• Internal clearance
• Cooling ventilation
• Dust-cover clearance

A correct H4 socket alone does not guarantee sufficient physical installation space.

CANBUS COMPATIBILITY NOTICE

Some modern vehicles electronically monitor their headlight circuits.

Depending on the vehicle, installing LED bulbs may cause:

• Dashboard bulb warnings
• Flickering
• Flashing
• Lights switching off
• CANbus compatibility errors

A separate compatible CANbus decoder, anti-flicker module or load resistor may be required on certain vehicles.

These accessories are not included unless specifically stated.

INSTALLATION GUIDANCE

• Switch off the vehicle and headlights before installation
• Confirm the existing bulb is H4 3-pin
• Remove the original bulb carefully
• Install the LED bulb securely
• Ensure the cooling fan has sufficient clearance
• Connect the H4 plug correctly
• Test both high and low beam
• Check the beam alignment before driving
• Ensure wiring does not contact moving or hot components

Professional installation is recommended if you are unsure about fitment.

MAINTENANCE & CARE

• Keep headlight lenses clean
• Keep cooling areas free from dust and debris
• Check electrical connections periodically
• Do not touch or damage the LED components
• Ensure the cooling fan remains unobstructed
• Check beam alignment after installation
• Inspect wiring for looseness or damage
• Replace both headlights together where possible for balanced illumination
