Horn sucks.

In a Real emergency, you Can scream. I'm very loud. You Can rap it up, flip the kill,, BANG,   Seems parking lots left me most ill at ease, but the
I'm turning left across your invisible butt
left me seriously worried.
My approach to getting their attention was weaving and flashing the headlight high and low. Some have called the wisdom of that into question, but I never saw anyone interpret it as
Ok, you can go.

The ironically named Hurt report shows what p percentage of injuries to the head are on what part of the head.
Not sure where I saw it, but Where we are, in traffic, can make us more likely to get turned across.

If you're leading Or trailing a string of traffic, you're more likely to be hit. The driver sees a long line coming, doesn't want to wait, tries to make it. Tag, you're it.
You're Last in a line. The driver is watching bumpers. The last Car in the line is Time to gun it..

YOU need to be either tailgating and near the passenger side or on the line, weaving a bit, and Ready to use the last car in the line as a shield.

Or, back off far enough to Allow safe traffic flow.

Watch heads, and front tires. The Top of a front tire shows more than the center.

Text them..

Any time one of my buddies sees me on mine I'll find a text on my phone, when I get off, that just says "meep, meep."

The horn is bad and sounds like something for a moped.  Does anyone know of a better horn that is a simple install, no relays or extra wires.

I wonder if mine is even weaker than what it's supposed to be.  

Since I live out in the country where people don't honk their horns much, I doubt I would know to use the horn if my life depended on it. I'd just get silently run over.  Maybe a "whoa!" or something at the most... Then, after it's all over, I'll think, "Darn it! Should have used the horn!"

Isn't it true that people out in the country don't use their horns much compared to city people? Lack of city driving and congested traffic? Over the years I haven't really gotten out as much as some other people.

Yup; horn sucks. Not something we need much in the hinterlands but on that rare occasion it would be nice to have one that worked.
