LED Headlight Color Guide - Choosing the Best Color

What's the best and brightest LED headlight color? Understanding the LED color chart.

Last updated: August 4, 2023


Automotive LED headlights, fog light bulbs, and conversion kits can come in a variety of colors.

LEDs (Light Emitting Diodes) generate light through a semiconductor, a material that emits particles of light when charged.

LED light is naturally bright white but it can be changed using colored lenses that slide over the bulb, like a sleeve.

In this guide, we'll walk you through the different LED headlight colors, and go over which is the brightest, and which is best for your needs.


LED Headlight Color Visualization Chart

Although most LED headlight and fog light conversion kits currently on the market come exclusively in white, we offer four different LED color options (yellow, white, blue, and purple).

The best way to decide which color you should choose for your LED bulbs is by taking a look at our LED headlight and fog light color visualization chart below.

What is the Brightest LED Headlight Color?

The brightest LED color for your car's headlights is white, approximately equivalent to a 5000K bulb color temperature in HID bulbs.

Although the light output is the same for each color, the human eye responds better to white light similar to natural sunlight.

As mentioned above, LEDs generate light through a material that emits photons of light when charged.

The light output (brightness) of LEDs is proportional to the amount of power supplied (wattage).

Therefore, the higher the charge the brighter the light emitted from the bulbs.

The charge, measured in watts (W), is provided by the LED drivers also known as the LED electrical circuit, which is the power supply.

At XenonPro, our LED headlight conversion kits come in three LED wattage options: 25W, 35W, and 45W.

For maximum brightness and the ultimate nighttime driving experience, we recommend going with our 45W LED kit in white, which produces exceptionally powerful, dense and wide bright white light.


Watts (W) to Lumens (Lm) Conversion Table

Power LED Halogen
25W 5000lm 800lm
35W 7000lm 1100lm
45W (brightest) 9000lm 1400lm
* Total light output from both headlights or fog lights

As you can see from the table above, 45W LED bulbs produce nearly 700% more light than your average halogen bulbs.

What is the Best LED Color for Automotive Headlamps?

If your objective is to see better at night and get brighter bulbs like most drivers the best LED color is white.

However, the 'best' color is subjective and entirely depends on your needs and ultimate outcome of upgrading your lights. The following summarizes the best LED color for different purposes:

  • Brightness: White
  • Style: Blue or purple
  • Like factory: Yellow

LED Color HID Equivalent Best for
White* (100%) 5000K Visibility
Yellow (90%) White (10%) 3000K Fog Lights
Blue (60%) White (40%) 8000K Style & Visibility
Purple* (90%) White (10%) 12000K Style

* Recommended; ** May be illegal in certain jurisdictions


Breaking Down LED Colors

White

White is the natural light color emitted from LEDs and closely resembles natural sunlight.

White LEDs are the brightest and are an excellent way to significantly improve visibility on the road at night. The light output and color will be identical to that of luxury vehicles equipped with LEDs such as Mercedes, BMW, and Audi.

Yellow

LEDs with a yellow lens will produce a color similar to halogen bulbs and fog lights but with significantly more light output.

This color is recommended for those looking to increase the light emission from their headlamps/fog lights while maintaining the same color as their stock halogen bulbs. We recommend yellow LEDs for fog lights.

Blue

Blue LEDs produce an ocean blue color that can be suitable for both a stylish look and improved nighttime driving. This color is ideal for those looking for a perfect balance between improved brightness and a stylish look.

Purple

Being a dark color, purple LEDs are unquestionably the least bright and are to be used solely for a stylish, street racer look.


Blue & Purple LED Headlights

Blue and purple LED headlights are becoming increasingly popular despite being the least bright.

Below, we take a closer look at the main advantages and disadvantages of blue and purple LED headlights and fog lights.

Blue/Purple LED Headlights Color

Pros

  • Stylish and expensive look
  • Unique headlamp colors

Cons

  • Least bright LED colors
  • Not recommended for fog lamps
  • May be illegal in certain jurisdictions
  • Ineffective during fog, snow, or rain

Best LED Color for Fog Lights

If you are looking to upgrade your fog lights to LEDs we recommend going with white or yellow.

We strongly advise against blue or purple bulbs for your fog lamps for your personal safety in times of poor visibility (fog, haze, rain, snow, etc.).

Frequently Asked Questions:

Lumens (lm) are a measure of light output and brightness. The higher the lumens, the brighter a bulb is.

Watts (W) is a measure of electrical power output. In the context of LED bulbs, a higher wattage will result in a brighter bulb.

HID colors are created through various additives, coatings, and gas mixtures inside the bulb. For more information on HID colors, visit our Ultimate Guide to HID Colors for more information.
