Good day to everyone.
Have to report that on Boeing 777-200LR Worldliner there are some cockpit lights not responsive when i push yheir related buttons. Soeaking about those to illuminate the cockpit cabin, not those related to instruments and screens. So i am forced to operate maneuvers in dark and with more difficulties to find and see the right buttons, lev ers, knottles for operating.
Referred to the dark hours flights/take offs/ landings.
I would like it if the development team would please fix those issues.

Thanks
