Pencil or Spot Beams - provide a longer narrower beam that focuses the pattern farther down the trail. These lights are designed to be used in conjunction with other wider beam patterns. Pencil beams come with a 10Â° wide pattern that can widened by 4Â° if desired. Driving Beams - Offer better peripheral vision than the spot while maintaining good distance projection. They can be used alone or with other beam patterns to create an excellent light system. Driving beams have a 20Â° pattern. Wide-Driving Beams - are slightly wider than a driving beam and are good for trail riding of filling in spots closer to the vehicle. They can be used alone or with other beam patterns to create an excellent light system. Wide-driving beams have a 28Â° pattern. Wide-Cornering or Fog Beams - are the widest and most evenly distributed light pattern of the bunch. These beams are used for lighting the ground close and to the sides of the vehicle and are great for turns and twists on the trail; it is also great in dust and fog. Due to its low and wide angle of dispersion, this beam should always be used in conjunction with other beams to provide the best possible lighting. Wide cornering beams have a 42Â° pattern.
