How do I determine the beam pattern for the off road spot and flood lights?
A quick note on the permanent mount off road lights. -W – denotes flood pattern (250 feet in depth and 200 feet in width) -M – denotes modified flood pattern (1200 feet by 135 feet) -S – denotes spot pattern – (2400 feet depth by 115 feet) The patterns are tear drop shape. The tear drop elongates as a spot or modified spot pattern. For example, 1870-W is a black, rectangular HID light with a spot pattern, while the 1870-M is a black, rectangular HID light with a modified spot pattern.
