# 27.1395 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 § 27.1389(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.
