Shopping Info H4 LED Headlight Bulb 9003 LED Bulb

Can I replace an H4 bulb with an LED?

All vehicles fitted with halogen headlight bulbs from the factory are suitable for LED conversion. The main advantage is a massive increase in road illumination and therefore improved safety when driving at night.

What is the brightest H4 LED bulb?

AUXITO H4 9003 Q16 Series 20000LM is the brightest H4 LED headlight bulb available for sale on AUXITO.

Are H4 LED bulbs high and low beams?

Yes. H4 bulbs are dual filament lamps, which means that each bulb contains two filaments. This allows them to be used as both high and low-beam lights with one filament for each beam.

Which direction do H4 LED bulbs go?

When you replace a halogen bulb with an LED bulb, it should work the same way as a halogen bulb. Place the LED bulb with the center tab facing up and the LED chip pointing horizontally left and right. If the bulb is installed tilted or upside down, you will get a strange and really bad beam pattern.

Are 9003 and H4 headlight bulbs the same?

Yes, 9003 and H4 bulbs are the same headlight bulb type. The 9003 designation is used in the United States, while the H4 is more common in Europe, but they share identical dimensions, so H4 and 9003 bulbs are interchangeable.

What are the temperatures of these H4 LED bulbs? , is it hotter compared to a halogen H4?

AUXITO H4 LED LED bulbs are designed with whole aviation aluminum, making the bulbs cooler than halogen. What's more, the Q16 series, Y13 series and M3 series H4 LED headlight bulbs are designed with a fan to provide superior cooling capabilities.

Which of AUXITO's H4 LED headlight bulbs are CANbus Ready?

AUXITO's Q16 and Y13 series are CANbus Ready and are compatible with 98% of vehicle computer systems without triggering errors.

I have flickering headlights after installing H4 LED headlight bulbs, how do I fix this problem?

You need additional H4 resistor decoders to avoid flickering.

Do I need a projector style headlight lens after upgrading my H4 halogen bulbs to H4 LED bulbs? Or will it still fit a reflector style and project a quality pattern?

AUXITO's H4 LED headlight bulb is not only fit for projector style headlight lenses but also for headlight assemblies with reflectors. Its ultra-thin substrate and 1:1 Beam design projects a high-quality pattern in factory headlight assemblies.
