# 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).

|  |  |  |
| --- | --- | --- |
| Green in dihedral angle | 10 | 1 |
| Red in dihedral angle | 10 | 1 |
| Green in dihedral angle | 5 | 1 |
| Red in dihedral angle | 5 | 1 |
| Rear white in dihedral angle | 5 | 1 |
| Rear white in dihedral angle | 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.
