Lighting is a challenging industry, particularly when connecting the light to your car. The basic headlamp connectors will be covered in this article. You’ve probably noticed various bulb categories if you’ve looked around the market for a new aftermarket bulb for your car. There are numerous varieties of headlights and fog lights, including HB3, HB4, H1, H3, H2, H4, H7, and more. Before today, did you understand the differences between the many types of bulbs and their purposes? Let’s take a closer look at these different light bulb and connector types and why they are set up the way they are.
Why are bulbs classified
There are many automakers worldwide, and these companies offer a wide variety of automobiles. It could have been almost impossible to get a replacement or even a bulb in the aftermarket if there were a separate bulb for each of the many autos. Okay, it would have cost a cent if a replacement bulb had accidentally been found.
Specific bulb classifications have now been created to standardize the bulb industry. Lightbulbs are one of the many automobile items whose worldwide standards are developed and maintained by the World Forum for Harmonization of Vehicle Regulations (ECE Regulations).
These light bulbs are first divided into three groups.
- Group 1 (H7 Bulb)
Most of the bulbs in a contemporary car are from Group 1. H7, H11, HB3, HB4, H1, H3, and H4 are a few of these. This category accepts and contains bulbs for fog lights. The connectors for the lamps are different, of course. Also, remember that not all the Group 1 bulbs will have the same power ratings.
- Group 2 (H6W Bulb)
Group 2 is the alternative classification. This package has numerous lights, including turn signal bulbs, tail light bulbs, license plate bulbs, and cornering light bulbs. Group 2 bulbs include C5W, H6W, HY6W, and other types.
- Group 3 (H2 Bulb)
Group 3 is the final group. These bulbs are no longer used and cannot be found in contemporary automobiles. However, these also include H2, C21W, and P19W bulb types.
Comparing bulb types
While most headlight bulbs might look similar, they also differ slightly which is why you must use these tips to choose your next bulb replacement. For example, the number of filaments, nominal power, and base type varies.
- Filaments
Others have two filaments, while some bulbs only have one. These headlight bulbs, also referred to as dual filament bulbs, are used to power both the primary and dipped beams. There is one filament set aside for each use. Drivers may find this simpler because there is only one headlight bulb. Single filament vehicles require two bulbs: one for the leading light and one for the dipped. Single filament bulbs include HB3, HB4, H1, H3, H7, and H11. Dual filament H4 is used.
- Nominal power
The light produced by these fittings is generally the same, but each bulb requires a different voltage and produces a different amount of power, sometimes known as nominal power. Most of these bulbs are offered with various nominal power ratings, which adds to the complexity.
It is risky to substitute one bulb fitting out for another, for instance, switching an H1 for an H7, because each bulb demands and produces a slightly different amount of power. This is why you should know the bulb that fits your car. Imagine connecting an American device to a European power socket; the appliance may overheat or suffer other damage. Car bulbs might experience the same thing. Fortunately, each bulb fitting has a distinctive base that makes it hard to mix them up.
It’s important to note that issues will primarily arise when changing fits. Unless you’re installing an aftermarket kit, changing your bulbs’ voltage or wattage shouldn’t cause any issues. Installing and using upgrade bulbs purchased from a dependable retailer is entirely safe.
- Base
The bottom portion of the bulb that attaches to the socket is called the base or cap. Another factor that makes it difficult to switch between fittings is these various bases. Consumers generally don’t need to care about the bulb base other than to ensure it matches their car.
