I'll be in the minority with you Texas. I don't turn on the strobes crossing a runway and I also don't turn them on when in positon and hold at night either until cleared for takeoff unless there happoens to be no one else waiting to takeoff. I prefer to be considerate. A flash or two of the strobes may not kill my night vision but it sure as hell is annoying. I'm betting the folks replying to this thread also like to blind people on taxiways with their taxi lights and landing lights too when crossing on a parallel taxiway head on. No beef if you're company books tell you to do so however. I don't buy the extra measure of safety being all that much or that big of an advantage. Not flying increases safety too...
