What is the best LED headlight kit?

While searching for a good-quality LED headlight kit or any other LED kit for changing the fog lights or day-time running lamps, make sure that you pick the right product for your vehicle. High powered LEDs need stable way to cool down; if they don’t it can cause heating issues. Another key factor is the LED chips and the placement of the chips. LED chip placement is important because it’s determines the light output pattern. Shopping online can get confused by the sheer number of sellers and LED lighting kits available on the web. Here at Underground lighting all of our LEDs are made to last and have the best light patterns to help you see. Call or chat with one of our helpful representatives today. We will be happy to help you to choose the perfect bulb for you.

Do you need a conversion kit to use LED headlights?

Give your car or truck an instant upgrade with “plug and play” installation, meaning that virtually anyone can have your bulbs switched out and ready to shine brightly in as little as ten minutes.

Can I replace my HID headlights with LED?

No, you can't. If the vehicle comes with factory HIDs you cannot convert to LED without heavy modifications and the visibility with a LED will be worse than the HID. Reason the headlight was designed for HID not LED. Call or chat with one of our helpful representatives today. We will be happy to help you and answer any additional questions or concerns that you may have.

Are LED Bulbs better in fog?

LED Bulbs are a better choice than Halogen bulbs in foggy conditions for several reasons. In addition to projecting an unmatched bright, white illumination output, LED bulbs are longer-lasting and, therefore, more dependable. The last thing you want when you’re on the road in less-than-ideal circumstances is limited visibility—this presents a potentially dangerous situation for everyone involved.

Are white headlights better than yellow?

When you’re on the road in inclement weather, or in low visibility conditions, such as extremely foggy or dark surroundings, bright white headlights are definitely the wiser pick over dull, yellow Halogen lights. Not only do efficient, environmentally-friendly LED bulbs look better and brighter, but they also do a much better job of illuminating the roadway for all drivers in the area. When you are on the road, whether you’re driving solo or transporting precious cargo, it is important to feel safe, secure, and fully aware of your surroundings. LED lights provide added security and peace of mind that make them well worth the purchase. Reach out to your team at Underground Lighting and let us assist you in choosing the best fit for your car or truck.

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.

Totally refreshed the trucks appearance. Bought the running lights a couple of years ago and was really impressed. I figured for the money I’d wait and see if the product was proven. Well Underground lighting delivered! Two years later (today) I’ve purchased headlights and fogs(LED). Last night I went out for a cruise to see what I had going on, well not to my surprise it was like driving during daylight! Very pleased! Thanks for taking pride in your work Underground Lighting!
