There are two kinds of LED headlights, one is a single bulb LED headlight; one is a integrated LED headlight with a lens. Single-bulb LED headlights require lenses, and integrated LED headlights do not require lenses.

 The luminous point of LED is different from halogen lamp, so the reflective bowl of halogen lamp is not suitable for LED lamp. The light emitted by LED will radiate, so lenses need to be installed. And all-in-one LED headlights, because of their own lens, do not need to rely on the original reflective bowl, the light type and brightness is better, can perfectly solve the problem of concentrating light.

Light is clustered through the lens, so it can radiate further. If the lens is not installed, not only can not give full play to the lighting intensity, but also cause dazzling trouble to the opposite vehicle.

 The modification of LED headlights can be roughly divided into the following categories:

1. Low light with lens, far light without lens. The modification condition is that the distance between the light sources is small enough. The light source is small enough. The LED headlights come with a spotlight cup.

2. The original car is a dual lens and can be installed directly.

3. Far and near lights have no lenses (most commonly in the Volkswagen series). The modification conditions are as follows: The LED headlight's luminous focus is similar to the original halogen bulb. The distance between the LED light sources is small enough. The LED headlights should preferably have a near-tangent function.
