What is an H4 lamp?

Before we get to the use and functionality of an H4 lamp, we would like to briefly explain what kind of lamp it actually is. In short, the H4 bulb is a halogen bulb that is generally used in the headlight. It doesn't matter whether it is a Cars or a motorcycle, because it can easily be used in both vehicles. The designation H4 is basically just an abbreviation for hardness level 4, which means that the hardness level is firm to very firm.

Basically, an H4 lamp is a Bilux lamp, which is a combination of incandescent filament and halogen technology. Inside there are two glow wires located in a glass bulb. While one wire is responsible for the high beam function, the second wire acts as a low beam, meaning that switching between the two lights is possible and possible at any time.

What are the differences between an H4 and an H7 lamp?

Many people ask themselves what the difference is between an H4 and an H7 lamp. This question is easy to answer because there are two completely different bulbs for headlights. You can find out what the exact differences are in the following H4 lamp guide.

• H4 bulb
  The advantage over all other headlight lamps is that it is possible to switch between low beam and high beam at any time without any problems. This is not least because there are two filaments inside the H4 lamp for car headlights. There is also a special pin assignment that has three pins. The disadvantage of the H4 lamp compared to the H7 lamp is the light output, which is essentially slightly lower.
• H7 bulb
  In contrast to the H4 lamp, the H7 lamp is one of the headlight lamps that impresses with improved road lighting and extremely high light output. Thanks to the simple base, these lamps are simple and easy to install and can also be used in a modern vehicle.

What should you pay attention to when buying H4 lamps?

If you decide to buy an H4 lamp, you should definitely keep a few points in mind. This not only includes the light color and brightness, but of course also the service life and range. Below we would like to briefly discuss the individual purchase criteria in detail.

• The range
  You have only chosen the right H4 lamp if there is enough light at the respective points. The ranges stated by the manufacturers are a legal standard, which are given in percent. Unfortunately, it is not possible to create an exact value for every vehicle as there are always differences in the height and depth of the headlights.
• The brightness
  A healthy average is very advantageous here, because the lighting should be neither too bright nor too dark. The appropriate permissibility is between 1402 and 1809 lumens and may deviate from this by a maximum of 15 percent. A higher value is not permitted as there is a risk of blinding other road users.
• The light color
  In our H4 lamp comparison we have already discussed the three different light colors, i.e. warm white, neutral white and daylight white light. Which light you choose at the end of the day is at your own discretion and you can therefore decide for yourself.
• The lifespan
  Unfortunately, brightness is very closely linked to lifespan. The brighter the H4 lamp shines, the higher the filling gas pressure is and the thinner the filament is. This in turn often contributes to significantly reducing the operating time. When buying H4 lamps, you should therefore make sure that you choose an average value in the brightness range in order to achieve a long service life if possible.
• The set
  It is often significantly cheaper if you choose an H4 lamp headlight set, so you always have a reserve. Many manufacturers, for example an H4 lamp from Osram or an H4 lamp from Philips, offer you suitable offers that are definitely worth comparing.

Is there an H4 lamp test from Stiftung Warentest?

Stiftung Warentest has not yet carried out an H4 lamp test. However, numerous H4 lamp comparisons on the Internet offer you a lot of information about luminous efficacy, general performance, brightness and of course lifespan. It is often about the quality of these lamps, because cheap H4 lamps often do not always offer the visibility and brightness that is required for optimal visibility.
