## CS 25.1395 Maximum intensities in over-lapping beams of forward and rear position lights

No position light intensity may exceed the applicable values in the following table, except as provided in CS 25.1389(b)(3):

| Overlaps                       | Maximum intensity        |                          |
| ------------------------------ | ------------------------ | ------------------------ |
|                                | Area A candela (candles) | Area B candela (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° but less than 20°; 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°.
