Why D-Series Lens?
Choosing the correct lens can mean the difference between getting a laser focused light beam in front of you, or losing much of the light to the sides of your vehicle.
Newer lenses, such as 4D, 5D, 6D, 7D, 8D, 9D lenses, focus much of the light directly in front of your vehicle. Older lenses, such as 3D, have much of the light wasted to the top and bottoms of the light bar, with very little being used to light up the road in front of you.
The amount of lumens won't mean much, though, if most of them are wasted because they come out of a 3D light bar. Does it fit my vehicle?
Our led light bars fit most vehicles(Off-road vehicle, Special vehicle, Engineering vehicles). But you need to measure the place where you want to install the light bar so that you can choose the correct size.
