Patterns: 
 
Driving/Combo:  Maximum trail coverage in a single light.  The Driving/Combo pattern is equipped with both Driving (42°) and spot (9°) optics to provide you with a smooth blend of light for both near field applications and distance (Lighting Zone 3) 
 
Wide Cornering: BD was the first to develop a pattern specifically for cornering, dust and/or fog conditions. The Wide Driving pattern offers a 42° flattened horizontal beam for the ultimate in comfort lighting. (Lighting Zones 1 & 2) 
 
Spot: A longer and narrower 9° beam focus for illumination further down the trail or road.  The Spot pattern is designed to be used in conjunction with additional Wide Driving and/or Driving/Combo beam lights. (Lighting Zone 4 & 5) 
 
Work/Scene: Excellent work light or “scene light” with an extremely smooth 120° circle that projects about 40ft.  This pattern is not suitable for driving. (Lighting Zone 7)
