C’mon — tell me you can’t think of a fun application for this $10 old-timey “oooga” horn from Harbor Freight! Think about it: it’s a 12V horn, so you could probably swap it into your car without too much hassle — or maybe into your significant other’s car, if you’re brave enough. If your ATV has a 12V system, it’d work great for clearing drunk dunderheads at your next back-woods booze-up.
And it’s way more interesting and useful than HF’s vaunted electronic fly swatter. No, really.
