I have no problem whatsoever with a dirty big blue VIPER symbol flashing on my dash window .... and it would seem the crooks do respect it, as I haven't had anyone touch my car (except for one small testing incident) and I park it everywhere. They also don't know it is the black wired version, I have 2 kill switches, and I have 4 of the loudest piezo screamers you have ever heard .... if their ears can take 30-90 seconds of those things going off in their ears while they hotwire the car, then they can have it.
