Why do you need the Best H4 Bulb?
If you are into car headlamps, you may be interested in getting the best H4 bulb for your vehicle. H4 bulbs were first introduced in Europe in the 1970s and became a very popular headlight because it can do high and low beams in a single bulb. Its popularity grew in Europe and spread to the US, where they are used on motorbikes and autos. The most common H4 headlight is a high-intensity discharge halogen bulb.
This is a very fancy way of saying that it is extremely bright at night. And because H4 bulbs contain two filaments, you have the option of putting them in high and low beams. In terms of wiring options, these bulbs usually have a three-prong attachment. They can give off a variety of colors from white to yellow, blue, and violet.
They can also be common in HID and LED form which usually requires some sort of conversion kit setup. The biggest issue with H4s hitting the US market was an issue with compliance. The HB2 was created in 1989 as a more compliant version of the H4. There is also the 9003 bulb, which is basically the same as the H4 in terms of connection type but just has more tolerance. It is not uncommon to see bulbs labeled as H4/9003.
However, today, there are plenty of H4 bulbs approved for use in headlamps complying with the US requirements. The biggest issue you need to figure out is whether you want your H4 in halogen, HID, or LED as H4 is simply the connection type. Halogens are the cheapest but have the shortest duration. HIDs are very bright but cause glare and maybe be street-legal. LEDs are expensive and require lots of initial setup and conversion kits.
