I just bought a Tridon LF12 loud flasher but, upon testing it, found it to be no louder than their common HD12 flasher. I tested it on the bench with a 50W load. Has anyone found the LF12 to be loud? I was walking by a courier step van last week and his flasher was really loud, you could hear it from thirty feet away. I am thinking of just soldering a piezo-electric buzzer to the terminals of the HD12.

Can't say about the flashers in particular, but, when I've wanted something similar I just go to NAPA or a big truck supply house. I imagine that TRIDON would be the supplier.
I used to carry mirrors, headlamps, wipers and HD turn signal flasher (loud) from tractor to tractor as a company driver. No flasher unit ever overcame any amount of wind noise.
Your solution sounds good to me.

Piezo-electric buzzers don't draw very much current so you probably won't see much of a change in the flash rate.
My 95 GMC Somona has the flasher buried in the dash where it's hard to hear a loud flasher. I remote mounted the flasher using some wire and standard spade connectors.
I glued the flasher to the hidden side of a piece of removable plastic on the dash (a blanking plate for some option I didn't have). The plastic acts like a sounding board and it's easy to hear now.
I can also change the flasher by popping a small blanking plate out instead of dissasembling the whole danm dash.
The piezzo buzzer idea sounds good too.

The light is dim and hard to see in bright daylight and I have better things to watch in traffic than the turn signal idiot light.
I like the solution of soldering on a buzzer.
I'm no electrical expert, but unless you use an electronic flasher as opposed to a "load" type flasher, the blink rate might be too fast because of the increased load the buzzer places on the flasher.

I heard of an old trick that someone took a tin can and cut it down to a quarter of its size and screwed it to the top of the flasher. It acted like a megaphone.
"resonance chamber" good idea, oilstain. Cadillac used to mount their horns with such mechanical advantage.
A lower viscosity blinker fluid is called...
seriously... many times just repositioning the flasher slightly (while working) changes the sound a world.

The tin can trick goes clear back to railroad telegraphers who used a Prince Albert can to amplify the sound of the actuator-it's the origin of the phrase "tin ear."
