I just purchased the TLR-2s for my home defense. I am totally impressed with the quality and brightness, but I can't get the strobe option to work. I tried to do what the instructions said but nothing happens. I even tried to reset it after 10 minutes of playing with it by momently flashing it nine times and holding on on the tenth try as the manual stated with no luck. Help! Wanna kill these ads?
