H4 car bulb

What is an H4 bulb?

The H4 lamp is a common halogen lamp used mostly for car or motorcycle headlights. Known for its ability to provide both two filaments, including a low beam filament and a high beam filament from the same bulb, this is actually a thrifty and very practical choice for many drivers looking for a reliable H4 car bulb .

Key features and benefits

The H4 car bulb is distinguished by its double filament, which allows switching between low and high beams. This means you can get a light that's powerful enough for tough driving conditions, while retaining a softer light for ordinary driving. With a basic wattage of 60/55 watts, the H4 lamp offers sufficient brightness capable of ensuring accurate visibility.

Key benefits :

• Versatility:Only one type of H4 headlamp lamp for both beams.
• Efficiency: Not too much power consumption.
• Cost: More affordable than other light bulbs.

How the H4 lamp works

The H4 car lamp works thanks to its two separate filaments: one for the low beam, the other for the high beam. When you switch on your low beam or dipped beam, the 55W filament lights up, and when you switch to high beam, the second filament lights up with it. This design enables a smooth transition between light modes, adapted to different driving conditions.

How to choose an H4 bulb?

Choosing an H4 bulb involves comparing several key aspects. First, look at brightness and color temperature to ensure good visibility. Then, compare H4 lamps with other types to assess their specific advantages and disadvantages.

Important features: brightness and color temperature

Brightness: H4 bulbs generally offer between 1000 and 1500 lumens. Opt for a higher value for better night-time visibility.

Color temperature : Choose a color temperature around 4000K for efficient, less dazzling white light.

Comparison with other bulbs

An H4 bulb comparison may reveal notable differences with other types. An inexpensive h4 bulb offers good value for money, but LEDs or Xenons can deliver better performance. Compare prices and features to make an informed choice.

For an informed choice of H4 car bulb, consider these essential criteria and make detailed comparisons.

H4 bulb applications
