# §84.05. Screens.

- (a) The sidelights of vessels of 20 meters or more in length shall be fitted with matt black inboard screens and meet the requirements of [§ 84.15](/cfr/33/84.15.md). On vessels of less than 20 meters in length, the sidelights, if necessary to meet the requirements of [§ 84.15](/cfr/33/84.15.md), shall be fitted with matt black inboard screens. With a combined lantern, using a single vertical filament and a very narrow division between the green and red sections, external screens need not be fitted.
