H4 car LED bulb

H4 LED headlight bulb: dipped and main beam in one LED bulb

The H4 is a bulb with two functions in one: dipped beam and main beam. Depending on your vehicle, the H4 fitting is used in the main headlight; you will also find it in many vans, trucks and motorcycles. Here you will find an H4 LED headlight bulb set of 2 with CAN-BUS, in daylight white 6000K and with up to 5000 lumens per bulb (manufacturer's specification). The set works on 12V and 24V, so it suits cars, vans and trucks.

What to look for when choosing

• Dipped and main beam: an H4 LED bulb combines both functions in one bulb, just like the original H4.
• CAN-BUS: designed for cars with an on-board computer, to help prevent bulb failure warnings on the dashboard.
• 12V or 24V: this set works on both, so one set for car, van and truck.
• Lumens and light colour: up to 5000 lumens per bulb in 6000K, crisp white light instead of yellow halogen light.

Will it fit your car?

First check which fitting you need: you will find it in your car's owner's manual or on the base of the old bulb. An H4 bulb has three contact pins and two filaments in one bulb. An H4 LED bulb is usually longer at the back than a halogen bulb. So check beforehand whether there is enough space behind the headlight and whether the dust cap still fits. Looking for an H4 LED bulb for your motorcycle? Space behind the headlight is often extra tight there, so measure carefully beforehand.

Laws and regulations

In the Netherlands, only LED retrofit bulbs that are European-approved for your vehicle are permitted in a halogen headlight. Therefore check beforehand whether use in the headlight or fog light of your vehicle is permitted in the country where you drive.
