You can wave, blink your turn signal (like a "wink"), flash your highs, . . . .
. . . . another good greeting is to have the FULL TIME AMBER's DRL's mod as an identifier/enthusiast of the Av club.
A friendly wave works great if you have the time to get one out . . . that way they can assume they are being greeted.
so i have to fix the DRL mine have not worked since the day i bought it thank you all just wondering Like the train horn Idea but i think the next MOD is a lift kit.
