Sorry, out of town for weekend.

Headlight mod's do not flash, rather they vary the brightness quickly -- slightly different than emergency vehicles that do flash.  By law, they are required to have a photoswitch to turn the headlight on normal mode at dusk.  Legal in 50 States, and Canada.

Anecdotally, I swear by them for helping to avoid cars pulling out in front of me, but no known studies have been done.  They are one tool for improving our conspicuity in traffic.  We also ride with flourescent green vests, what road workers wear:  really helps in rain and fog, and the very occasional night ride.  Received numerous compliments at gas stations, from current, and retired, law enforcement officers.  These vests are becoming more common on the roads in my area as well.

Different modulator models are available.  Some plug into the back of the headlight (most expensive models), others require cutting into the wiring (less expensive).  My oldest is 5 years, still works perfectly (JC Whitney's Amperex model -- required a bypass toggle swith, no photoswitch).  Bought a higher model, with auto-magic photoswitch, directly from Amperex ($60 delivered), put it on my Voyager.  Works great, but the photoswitch needed some shades as it stayed on at dusk, when I thought it should be off.  Cut a $3 sunglass lens with a cut-off wheel on my mototool, secured with RTV Silicone -- works great.  Probably more than you wanted to know...  Cheers!
