FAQs

Frequently Asked Questions on LEDs

Which Color Is Best for Headlight Bulbs?

The best color for your headlight bulbs is white. You want to find a bulb around the range of 6000k in color temperature. The human eye reads this color and brightness better due to its similarity to natural sunlight.

That said, the best color for your headlights can be subjective. LEDs are also available in yellow, blue, and purple. Each color will work just fine on the roads and give your car a more distinctive look than the traditional white color.

Will LED Headlights Damage My Car?

No. LED headlights will not damage your car if properly installed. In addition, you want to purchase the correct LED light that will fit your car. For example, if your vehicle has a CANbus system, you want to buy the right product and install it correctly to avoid any potential issues.

If your car was not originally designed for LED headlights, you can purchase an LED headlight conversion kit. They are safe and will not damage your vehicle as long as you buy top-quality products.

Why Are LED Lights Better?

An LED light bulb saves more energy, produces less heat, and has more light. In addition, it uses 85% less electricity than standard lighting. It is also a lower-cost product but has bright light with a longer life span.

LED light is different from incandescent light. Blue LED combined with yellow phosphor creates white light. The high efficiency of LED light makes it a popular choice.

What Is the Purpose of LED Lights?

LED lights are used as a light source in our homes, devices, and vehicles. LED (light-emitting diode) lights use gallium compounds such as gallium arsenide and aluminum gallium. LED emits light by combining a P-type semiconductor with an N-type semiconductor. Once a voltage is applied, they release energy into light.

What Is the Lifespan of LEDs?

LEDs have a long life span. When an LED is operating at 70% capacity, it has reached the end of its life span.

Incandescent bulbs have around 750 to 2,000 hours of light. In comparison, LED bulbs can have 50,000 to 100,000 hours of light, making them better investments.

Can I Replace Incandescent Bulbs with LED in My Car?

Yes! You can change your initial bulbs to LED in your vehicle. In addition, there are different places where you might want to swap out for LED lights. For example, you can change your headlights, rear license plate lights, interior door entry lights, rear brake lights, and more.

First, however, you need to inspect what type of bulb you need. There are different bulbs with various designs, so you must buy the right one to fit.

Second, different areas of your car may require special tools or specific parts to work properly. Once you have found the products you need, you’re ready to go LED.

Very Bright

Ordered the back up lights for my 2017 GMC Sierra. They’re much brighter than the OEM and gives the truck a newer appearance.
