What is the difference between h4 and h7 bulbs?

[DelMolly]

Here are the differences between h4 and h7 bulbs: 1. H4 and H7 are two different types of bulbs with different functions and structures. H4 is generally used for high and low beams, while H7 is typically used for low beams. 2. H4 has three terminals and features dual filaments for high and low beams, whereas H7 has two terminals. 3. H7 has a wider illumination range but shorter distance, making it less noticeable for stationary dark-colored objects on the road. H4 combines both low and high beams in a single bulb, serving dual purposes. Here is some related information: 1. Car headlights, also known as car front lights or LED daytime running lights, act as the eyes of the car. They not only affect the external image of the car owner but are also crucial for safe driving at night or in bad weather conditions. 2. Car bulbs are essential for ensuring driving safety at night. Poor lighting conditions can easily cause eye fatigue and fail to provide adequate brightness and illumination range for the driver. High-quality car bulbs can offer higher brightness and better visibility, enhancing driving comfort and safety, ensuring confident driving.
