Quick question

[Tomahawk674]

Very easy question.

 

On the the Su-27, I mostly use the HUD for payload information, but I know right beneath it is a row of green and yellow lights representing hard points. I understand green means active or selected missile type. What are the yellow lights above representing?

 

I knew if but I forgot, can't find it in the manual.
