Everything you need to know about the H4 bulb

You have repeatedly wondered what the H marking in front of the numbers means in the context of car bulbs. H1, H4, H7 and many more H to choose from! Today we will focus on the H4 light bulb, what it is, what it is for and how much it will fly with us!

The h4 bulb is a type of halogen bulb with two filaments and supports in our car: high beam and low beam or high beam and fog lamp. A fairly popular type of light bulbs, long used in the automotive industry, with a power of 55 W and a light output of 1000 lumens.

Since H4 lamps use two filaments, there is a metal plate in the center of the lamp that blocks some of the light emitted from the filament. As a result, the low beam does not blind oncoming drivers. Depending on the operating conditions, the H4 bulbs should be replaced after approximately 350-700 hours of operation.

Subsequent technological solutions and innovations in the design of halogen lamps meant that the new lighting has additional properties compared to traditional halogen lamps. It is important to note that these improved lamps are not only intended for newer car models, they can be used in the same headlamps used for traditional halogen lighting.
