After reading all the comments I tried a little experiment. I rigged up two aircraft landing lights under the rear bumper of my wife`s Jimny. Took a ride to Al Khor and sure as hell flashing lights in the rear view mirror. As our superhero in the big Landcruiser got closer flashing like mad, I decided to greet him back. Flick of the switch and voila!! He did not want to communicate in Morse code anymore. Maybe he was stuck for words. Word of advice carry extra batteries!!
