Sec. 25.1391 — Minimum intensities in the horizontal plane of forward and rear position lights.
Each position light intensity must equal or exceed the applicable values in the following table:
|Dihedral angle (light included)||Angle from right or left of longitudinal axis, measured from dead ahead||Intensity (candles)|
| L and R (forward red and green)||0° to 10°|
10° to 20°
20° to 110°
|A (rear white)||110° to 180°||20|
