I went through a variety of flasher modules including ones that are supposedly loud, and concluded none are loud. I got tired of being one of those guys that drives down the road for 30 miles before realizing my turn signal is still on. So this is what I did. I bought a small solenoid from eBay, and cut the bottom inch off of a food can, and used a popsicle stick and construction adhesive to position the solenoid so it will hit the can bottom when energized. I turned in the sharp edge of the can and used pliers to crimp it down to make a smooth non-hazardous can edge. I cut a slot in the can and used a hose clamp to put it on my steering column. I wrapped a piece of solid 18 gauge wire to the bottom leg of my turn signal flasher for one of the solenoid connection wires, and connected the other wire to ground. It make a pleasant, crisp, and loud clack that I can hear over road noise, fairly loud radio, and engine.
