NOT THAT I'M ARGUING...But...In Texas...I've never had an inspection problem with a missing reflector on a motorcycle. On my VTX, the front fork reflectors had fallen off and the rear license plate reflectors where removed a long time ago.
I would agree with Steve/53Driver that reflectors are required but our lax inspectors don't look for reflectors.
I also did a search for Whelen TIR3 and found them HERE.
