I have the Blinder M45X laser jammer and I was testing it tonight w/ my TV remote, when all of the sudden my Bel STi driver laser alert went off.
I shot my CD remote right at the Bel and nothing.
I then reshot my blinder and viola...my Bel went off again. Apparently the Blinder shooting back at my remote hit my garage door and reflected into my STi (which thought it was getting a laser hit).
Anyway, I'm sure someone else has figure this out already, but I though it was a fun way to test that your radar's laser senor was functioning.
