I installed a Radio Shack buzzer by soldering the red wire to the X terminal and black wire to the L terminal on my 3 pin flasher. I saw many people on these threads complain about how loud their buzzers were, so I made sure I bought the quietest one I could. The one I bought is a 76 dB Piezo Buzzer. I see they also have 85 and 100 dB buzzers. Those might be what others used. I am pleased with the 76 dB one. It is loud enough that you hear it under the dash and want to turn it off but not so obnoxious it bothers you. I velcroed the buzzer to the top of the flasher can.

After I bought it I found this thread that says that Mac's has a flasher with buzzer integrated for both 6 and 12 V systems. I see on-line they are still available. I probably would have purchased that if I had known about it, but they are fairly costly. They were $27 for the 12 V and over $30 for the 6V.
