eureka

I think I have lighted on something.

If the sentence below is correct,
1. I am panicky about my upcoming English exam.

Then, so is the sencond sentence.
2. The US soldiers were panicky at the death of their captain.

Preposition "about" is used for general relation in this sense, whereas "at" is used for specific sense.

Although it may sound unnatural to some English natives, it is grammatically correct. Thanks.

Thank you for the interesting information.

I had never thought about it before.

You have, indeed, lighted/lit on/upon something!

Thanks again for sharing it with us.

I appreciate your acceptance on it, thanks.
By the way, why did you say "I had never thought about it before." (past perfect) instead of using present perfect, just as:
"I have never thought about it before."
To me, present perfect will do in the sentence, but I want to learn something new from you, because there is a reason for it.
Thanks ever so much.

***** NOT A TEACHER *****

(1) Thank you for your kind note, panicmonger.

(2) I am just an ordinary native speaker, so I don't know whether I can really answer your question why I chose the past perfect.

(a) Maybe (maybe) my complete thought was something like:

I had never thought about that before (I read -- past tense -- your post).

Have a nice day!

I didn't think about it. Then I thought about it. Once you start to think about it, your action of "not thinking about it" is past.

I have never thought about this -- I'm still not.
I had never thought about this -- I am now thinking about it, or have now thought about it.

appreciate your acceptance on(should be 'acceptance of' it), thanks.

"I have never thought about it before."

The present perfect would not do. Present perfect, as the name implies, is used for an action that continues to the present as Barb said.
