LED lighting has been around for over 50 years. LEDs are semiconductor diodes that convert approximately 90% of the electrical energy they consume into light energy. Standard incandescent light bulbs have a conversion rate of only about 15%. LEDs last considerably longer than incandescent bulbs. Service life is typically in excess of 30,000 hours and can go up to 100,000 hours. They don't...

　　The H4 car bulb is used for headlights, it contains two filaments, and you can choose a high beam and low beam in one bulb. So if your car is suitable for H4, you only need one set of bulbs to achieve the effect of high beam and low beam. If using other types of headlights, you will need to purchase 2 sets, one for high beam and one for low beam. 　　This bulb has a three-prong attachment on...

　　If you've been thinking about upgrading your car light bulbs, you've definitely come across the terms "xenon" and "HID." A popular feature on many modern vehicles, HID car xenon lights are a great way to add a stylish touch. 　　Xenon headlights have been around since the early 1990s and have grown in popularity since then. You'll be able to spot these headlights easily on the road...

　　Everyone is familiar with burnout light bulbs. In household lamps or lamps, when the filament overheats and breaks, it is often accompanied by a flickering, sometimes humming, or loud popping sound. A burnt-out car headlight is usually a more subtle event. If you drive mostly during the day, you might not even notice it, but a headlight or taillight could burn out and stay dead for...

　　Traditional incandescent lamps work by driving current through a metal filament in the middle of the bulb. As a result, the filament heats up to the point where it begins to emit light, providing illumination. HID car xenon lights are different. Instead of relying on a filament to provide light, HIDs drive an arc through a chamber filled with an inert gas (usually xenon). This is a...

　　Car LED bulbs refer to the use of LED technology for both the interior and exterior light sources of the car, which are used for exterior and interior lighting. External lighting involves thermal limits and EMC issues, as well as many complex criteria for unloaded load testing. LED car lights can be widely used to create a car interior environment, with a service life of 50,000 hours....

    H7 is the model of the bulb. Models are H1, H4, H3, H7, etc. 1.H1 is a high beam bulb; 2.H3 is a fog light; 3.H4 is a light bulb with both far and near beams; 4.H7 is mostly a low beam bulb, but some are also used as a high beam, such as AUDIA6. Among them, H1 is a single-wire one-legged light bulb, H7 is a single-wire two-legged light bulb, and H4 is a double-wire...

LEDs are solid state devices (SSL). They won't burn out. With a lifespan of over 30,000 hours, this means that while it costs more, you have less maintenance to do, and over time you'll find that they pay for themselves. Because they require very little energy to light, they put less stress on old wiring and electrical systems. 　　Our dashboard LEDs are dimmable, but this depends on the...
