I have a Surefire M900 mounted on my AR, and the LED's are EXTREMELY dim, I have new batteries in it, so can anyone give me any ideas as to why they are so dim, and if there is a way to fix them?  They are the red LED's, but when you press the thumb activation switch you can hardly tell they're on.
