The term Scottish is ambiguous. It could mean the dialect of English spoken in Scotland (think Robert Burns) or the Scottish Gaelic (Celtic) language. If the latter is intended the question should be phrased 'How do you say light in Scottish Gaelic'.
Furthermore, the question could be more easily answered if it were used in a sentence.
"I saw the light." "It was light in weight." etc.
"Licht". Straight from German, but similar to the other Teutonic languages, as well as Scottish.
Scottish English or Scottish Gaelic?
Scottish is not a language
To say "funny" in Scottish, you can use the word "fun."
You say 'peace be with you'
No. Solas is the Scottish word for light. Sorcha means "light, radiant" it's the Scottish equivalent of Lucy or Lucia. The only name I know of the literally means "bringer of light" is Lucifero, aka Lucifer.
