Thought I'd take a look at this component so I downloaded it from Git hub.
Something I have gotten used to is the very frequent failure of Lazarus code to actually work out of the box.
When installing the package using its lpk
It fails to compile
FGlyphs[lsOn].LoadFromResourceName(HInstance, OnBitmaps[LedKind]);
Not entirely unexpected due to the dependency within dependency and the sometimes lexigraphic nature of Lazarus.
IDE v1.0.12 (no ooze to other directories) all files contained within the folder Lazarus. Windows 7 pro 64 bit
There is a resouces folder with the png's and xpm files
