I have but most don't flash their high beams at me. I think they automatically assume that with the three lights coming at them we must have our high beams on. When they do flash their lights at me I return the favor with my high beams!I bought a bunch on ebay with amber, clear and dark and I really like the ambers for at night. They keep the anti glare down quite a bit. On the same topic of night riding anyone else have guys flashing the high beams at em when running with the spot lights on?
