In automotive lighting, selecting the right headlight bulb is crucial for performance and safety. Different car models require specific bulbs to achieve optimal upgrades. Among the many available options, H4 and H7 bulbs are the most commonly used types. This blog will compare H4 and H7 headlight bulbs to help you understand their differences.
What is The H7 Car Light Bulb?
H7 car headlights are widely used in modern cars, especially German and other European-made models.
Since it was first introduced in 1993, the H7 automotive headlight bulb has been popular. H7 bulbs are single-beam headlamps, which means that each bulb has only one filament and can be used for either low or high light.
Typically, H7 bulbs are primarily used for low light, while high beam bulbs require another single filament bulb, such as the H1 (depending on your vehicle type). The H7 bulb uses a two-pin connector, making it easy to install.
What is The H4 Car Light Bulb?
The H4 car light bulb was originally designed for racing cars and was mainly used in European cars. In the United States and India, H4 bulbs are popular on motorcycles, but cannot be used because they do not meet automobile safety standards.
To solve this problem, 9003/HB2 bulbs were developed that are suitable for road cars and do not dazzle other drivers. The main difference between H4 and 9003/HB2 bulbs is their base. The 9003 bulb has three equally large metal protrusions, while the H4 bulb has a shorter metal protrusion.
With the development of headlight technology, H4, HB2 and 9003 bulbs are now interchangeable. Many light bulbs carry these labels on their packaging.
