With the attachment lens called the Reeded Lens| the beam angle of the triple-R headlights can be increased from 5°| 10° to 30° depending on the model. Thus| the headlights can be used| for example| both on the road and in off-road applications| where wider radiation is desired. If| for example| four headlights are mounted in both horizontal and vertical arrangement as cornering light in rally vehicles| then the dark zones resulting from the attachment can be illuminated by two lenses.

The Reeded Lens is made of acrylic glass| covers 4 LEDs and is fastened with clamps. A seal prevents the dirt and water to get between the lens and the headlight glass. The Reeded Lens can also be mounted on headlamps with more than 4 LEDs and then give them a hybrid radiation profile.
