Description

Pressing 'L' during a Kerbal EVA should switch on their helmet lights. This no longer works on the version I am using (1.1.3.1289 x84 Win10)

I am not the only person to have run into this bug:
http://forum.kerbalspaceprogram.com/index.php?/topic/144426-what-happened-to-the-helmet-light/

Apparently there is a stock fix available, so should be very easy to fix in an official version:

"Update 1.1.3a.1:

Deprecated several modules (that have been incorporated into stock)
Added a small fix for non-responsive kerbal EVA lights"

Can confirm on 1.1.3.1289 x64 Win 7 though, as only personally experienced on modded saves, only tentatively. Happened when EVA'ing around a very part heavy (such that the mission clock was nailed yellow) space station.

I can confirm this happen on some keypresses, but on others it work as it should.
The reason is probably that the 'L' key state is checked in some FixedUpdate(), instead of Update().
This lead to the input button state being not consistent as there are usually multiple FixedUpdate() calls for each frame.
But the input system is updated every frame, so in some FixedUpdate() you get lucky and the state is correct, but in others isn't.
