Light Color

As with all lights, the light output will be a certain color and referred to a Kelvin rating. The Kelvin temperature chart determine the output color of the bulb where the majority of LED lights fall between 3,000K and 6,500K. Opting for a light color over 6,500K often results is a blue hue to the light, which may not be street legal.


Some car owners may want the brightest LED headlight bulbs they can get their hands on. If this is the case, you will want to pay attention to the Lumens ratings of each bulb. The higher the rating, the more brighter the light output.

Heat Emission

One drawback of using LED headlights is that they produce heat when used for long periods of time. This is because LED bulbs use semi-conductors, which rely on temperature for its performance as a diode is required for low temperature output.

Therefore, you should ensure that the conversion kit uses a cooling system for heat dissipation to avoid any premature breakdown of the bulb due to excessive heat.

CanBus Light Malfunctions

A common issue that many people come across is the dreaded CanBus warning light due to incompatibility with the vehicles computer and the new bulbs. No matter how many times you remove the error with a car diagnostic tool, as soon as you turn the light bulb on, it will reappear.

In order to overcome the issue, we highly recommend that you have installed the capacitor between the bulb plug and socket correctly. Loose connections is a popular cause for the CanBus error and it can be solved fairly easily.

Are LED Headlights Road Legal?

When it comes to purchasing LED headlight bulbs, you will want to pay close attention to your state laws. There are laws that restrict street usage of bulbs that output certain colors (i.e. outputting blue light) or bulbs that are simply to bright. For example, in Indiana there is a specific ruling for blinding lights as shown here.

However, the bulb itself is not the main issue, it is the reflector. This is because if your headlight reflector has been designed for halogen bulb, it will distort the beam pattern from the LED light. This has the effect of spreading the beam output, which can frustrate drivers on the other side of the road.

The likelihood of getting pulled over for using LED headlights is very unlikely as long as they are not blinding other road users. However, you should be warned that the majority are not DOT certified and may get you in trouble.


Introducing LED technology into your vehicle in the form of LED headlight bulbs can truly transform the appearance of your car. Not only that, they also produce additional visibility on the road, which makes night driving more safe.

Installation with conversion kits is made simple and all of our recommendations in this article are highly rated. Most people will not be too bothered but you should check the state laws regarding the LED bulbs you purchase as not all the kits you find are not DOT compliant.
