(e) For day operation, all fuses or circuit breakers to electric equipment used during such operation must be accessible to the pilot in flight. (f) To make airplane eligible for night operation: (1) Type A-9 wing position lights (AN 3033-5 through -8) should have the frosted area on the inside of the glass cover painted black. (2) Replace Type D2 tail position light with certificated light. (3) Remove position light resistors. (4) Install 15 ampere fuse or trip-free circuit breaker in landing light motor circuits independent of the 35 ampere circuit protector in the filament circuit if landing lights are to be used, otherwise the landing lights shall be made inoperative. (5) All fuse and circuit breakers must be accessible to the pilot in f light for replacement or resetting respectively. (g) A battery switch shall be installed to disconnect battery circuit within distance not exceeding two feet of the battery. (Applies to L-5, L-5D, Serial Nos. 1 to 276, inclusive only).

(l) If non-trip-free circuit breakers are installed in electrical circuits, they should either be replaced with fuses prior to certification or with trip free breakers as soon as the latter become generally available. (m) Mark instruments for approved operating limits. (n) Plastic type elevator trim tab, if installed, must be replaced by a metal type tab. Airplanes now equipped with the standard metal trim tab in use on most L-5 series airplanes need not be revised provided the C.G. limits listed under Part I are maintained.
