Important Notes - Please Read Before Purchasing

Socket Type Verification - This ad is for H4 3-pin type bulbs. Before purchasing, ensure your vehicle uses H4 headlight bulbs with a 3-pin connector. H4 bulbs are common in many vehicles and feature dual filament design for high and low beam.

Projector Housing Recommended - This bulb is optimized for projector headlight housings. While it can work in reflector housings, projector housings will deliver the best beam pattern and cutoff.

Polarity Check - This bulb requires correct polarity to function. If the bulb does not light after installation, disconnect and reverse the plug orientation. Ensure positive and negative connections are properly aligned.

Hi/Low Beam Function - H4 bulbs have dual beam functionality. Ensure the bulb is properly seated and oriented to allow both high beam and low beam to work correctly.

Dust Cover Fitment - Due to the built-in cooling fan, the bulb assembly is larger than standard halogen bulbs. The original dust cover on your vehicle may not fit over this bulb. Consider purchasing aftermarket extended dust covers if needed.

Correct Fitment - Ensure the bulb is fitted correctly and securely seated in the headlight housing. H4 bulbs are secured with a retaining clip. Improper installation may affect beam pattern and performance.

Canbus Compatibility - This bulb may require a Canbus decoder for some vehicles with sensitive electrical systems. If you experience flickering or dashboard warnings, an external decoder may be required (sold separately).

Important Considerations Before Installation

Verify your vehicle uses H4 3-pin bulbs before purchasing.

Check that your vehicle has sufficient space for the bulb assembly with the built-in fan. Some vehicles may require removal of the headlight assembly or battery for access.

Test bulb polarity and both high and low beam functions before final assembly.

Ensure the retaining clip is properly secured to hold the bulb firmly in place.

For some vehicles, additional decoders may be required to prevent flickering or dashboard warnings.

Projector headlight housings will provide optimal beam pattern and cutoff.

Simple Care Tips

Handle bulbs by base only - avoid touching LED components.
Ensure bulb is securely held by retaining clip.
Ensure cooling fan vents are not obstructed after installation.
Keep headlight lenses clean for optimal performance.
Check beam alignment after installation.

Safety Warnings

Ensure engine is off and headlights are cool before installation.
Wear gloves to avoid skin oils on bulb surfaces.
