again.... mine is a set of 2 horns! NICE!
i looked at hornblasters but they require an air tank.
i also looked at PIAA and Hella but they sound like a loud European car. i wanted a deep train sound without an air tank and these have it! they're out of Chrpus Christi and i'm in DFW so i'll have them in this weekend. i'll get back to you guys with a clip!
