Why are you "clearing" your house? What is your objective? Do you have family members in a remote location that you need to reach? What is the cost vs. benefit of "clearing"?
Ever hear of using a verbal challenge?
- WHO'S THERE?!
- I HAVE A GUN!
- I'VE CALLED POLICE!
- GET OUT NOW OR I'LL SHOOT!!!
That *should* take care of most nightime burglary situations you find yourself in.
If you have to exit your safe room, you don't use the light to "search." You use the light simply to identify the threat before you shoot.
You don't have to point your gun directly at the threat to illuminate it, you splash light off the ceiling, floor or wall.
I'm also equipped with a hand carry Surefire, which if my gun mounted light fails and I need to shoot the target, then I retract it to my center neck as I bring the gun up to fire from a one-handed SUL type carry, either extending my firing arm or bringing it back to fire from a retention position.
Cheers!
