It was almost five years ago when you asked it, but as the other friend says "you might be helping someone else". You did help me. I own both Trooper and Stryker. Less than a week i bought Trooper, the LED in the middle didn't turn on again. As it was the last one available in the store i didn't want to take it back and probably miss the opportunity of having it. I wanted to change LED by myself but as it happened to you i didn't know what type it was until now i'm reading it. Now i'm able to buy it and change it. Thanks a lot.
