Although, I have driven with a V1 for so long (about a decade and a half) I don't rely at all on the visual identifications. The shortest path to ones brain, IMO, with a detector is its sound
. In most cases, my foot is already hitting the brake before I visually check the detector.
I've seen the multi-color customized jobs for the V1 and they are intriguing and would certainly expedite the speed to ascertain which band you are getting hit with in the event you can not make an audible determination alone.
Good luck with whatever way you go. If you happen to get the multi colored led system, please let me know how it turns out.
I believe I have already seen hookups for integrating the V1's alerting into an automobile's in-dash display. I recall reading online a BMW setup that looked pretty cool.
