Beam Guide In addition to the multitude of technologies used to produce the light, there are multiple light patterns that customers need to be aware of. The various light patterns are easy to understand when you see them together. The views in the accompanying graphic give you a birds-eye view of what each beam looks like on the ground. Standard headlights have a unique beam to illuminate the foreground well and then angle off to the right at a distance to minimize glare to oncoming traffic. The rest of the beams are symmetrical in their pattern.
