What Is The Car Bulb Classification?

The UN has classified car bulbs into different types to create international standards. By doing this, it guarantees that bulb types will be the same in various countries.

UN Regulation 37 provides guidelines for how different types of bulbs can be used. Bulbs are grouped into three categories: Group 1 can be used for anything, including headlights and tail lights; Group 2 can be used for signaling lights but not for bulbs that illuminate the road; and finally, Group 3 comprises lights that are no longer used on new vehicles but which manufacturers can still produce as replacements for older vehicles.

What are the numbers on bulbs? A bulb code is composed of numbers that indicate the size of the base in millimeters or eighths of an inch.

For example, let's take a look at A19: The 'A' denotes that the bulb has a standard household shape while the '19' specifies that the base is 19/8th inches wide. Knowing the bulb code helps you determine the shape, size, and wattage of the bulb.

So if you ever find yourself lost in a sea of bulb part numbers and don't know which one to choose, just remember: A19 is a household-shaped bulb that has a base width of 19/8th inches and an A can stand for anything! Now you're ready to make your purchase with confidence.

How Do You Read A Light Bulb Part Number?

The light bulbs are classified by a code that consists of one or more letters, followed by a number. The letter(s) indicate the shape of the bulb, while the number indicates the diameter of the bulb in the eighths of an inch. The most commonly used household light bulb is known as an A-19.

There are car bulbs that don`t have a letter in their part number or have more than one letter. The numbers in the part number indicate the diameter of the bulb base in millimeters and watts. Some bulbs will also include a letter at the end which denotes the color temperature of the light output.

For example, an H4 bulb is usually used for car headlights and has a base width of 4/8th inches and a wattage of 55W. An HB3 has a width of 3/8th inches and a wattage of 9005W, while an HB4 has a width of 4/8th inches and a wattage of 9006W. Knowing this information can help you choose the right bulb for your vehicle.

Does Socket Type Matter?

The socket is what type of bulb you need to purchase. The type of socket determines the voltage, wattage, and other characteristics needed for a bulb to work properly in it. When purchasing bulbs for your vehicle, make sure to check the socket type required. While some parts may look similar, they may not be interchangeable due to their different electrical requirements.

So if you're ever stuck trying to shop for car bulbs, don't worry - just remember these tips about bulb part numbers and socket types! With this information in mind, you'll be able to find the right replacement quickly and easily.

The base, or cap, is the bottom part of the bulb that connects to the socket. These different bases are another part of what makes it impossible to simply switch between fittings. Most consumers only need to worry about the base of their bulbs when they're changing them out - otherwise, as long as it fits in your vehicle's socket, you shouldn't have any issues.

How Do You Match Light Bulbs?

The wattage of a light bulb is the amount of energy it uses, often from 40 to 120 watts. All light fixtures have a maximum wattage that shouldn't be exceeded. To choose the right light bulb for your fixture, ensure that its wattage doesn't exceed the maximum for your fixture.

The socket type of your light fixture is another important factor for matching the right bulb. The socket type of your light fixture will tell you the size and shape of your bulb—E26 bulbs are standard, but other sizes include E12, E17, and more.

For halogen bulbs, in particular, make sure to look out for their wattage: halogen bulbs use more power than LED or CFL bulbs.

Finally, always double-check the voltage rating of a bulb before installing it; some fixtures have special requirements that should be taken into account when searching for a replacement part.

Now that you know what to look out for when matching up lightbulbs to your vehicle's needs, you can start shopping with confidence! With this knowledge in mind, it's time to get out there and switch up those bulbs.

Can Any Light Bulb Go In Any Fixture?

You can use an LED bulb in any fixture as long as the mounting base (socket) is the same size and type. If it isn't, then the LED bulb will not fit into that socket. Additionally, you should never use a higher-wattage bulb than what is recommended for your particular fixture. Thus, if you have a fixture that requires a maximum of 60-watt bulbs, you should not use a 75-watt bulb in it.

Ultimately, when it comes to lightbulbs and fixtures, it pays to do your homework! By taking the time to understand bulb part numbers and other technical details, you can make sure you're getting exactly what you need for your vehicle.
