Light pattern is Nordic Lights’ preferred term for the shape and distribution of light produced by a lamp. The correct pattern depends on the vehicle, mounting position, task, speed, and required viewing distance. Nordic Lights pattern names include Flood, Wide Flood, High Beam, Reverse, Glare-Free, Super Wide, and Pencil Beam where available. A suitable pattern places enough light on critical objects and surfaces while avoiding excessive foreground brightness, dark gaps, reflections, and glare. Multiple patterns may be combined around a machine to cover travel, task, side, rear, and attachment zones. Photometric diagrams and application testing help determine lamp quantity, position, spacing, and aiming.
