14 C.F.R. § 25.1395 — Maximum intensities in overlapping beams of forward and rear position lights.
§ 25.1395 Maximum intensities in overlapping beams of forward and rear position lights. No position light intensity may exceed the applicable values in the following table, except as provided in § 25.1389(b)(3). Overlaps Maximum intensity Area A (candles) Area B (candles) Green in dihedral angle L 10 1 Red in dihedral angle R 10 1 Green in dihedral angle A 5 1 Red in dihedral angle A 5 1 Rear white in dihedral angle L 5 1 Rear white in dihedral angle R 5 1 Where— (a) Area A includes all directions in the adjacent dihedral angle that pass through the light source and intersect the common boundary plane at more than 10 degrees but less than 20 degrees; and (b) Area B includes all directions in the adjacent dihedral angle that pass through the light source and intersect the common boundary plane at more than 20 degrees.
