X2 for Turnswitch.com - best turn signal system available, and 100% solid state that functions w/o requiring a pesky flasher. Features include easy accommodation of 3rd brake light, self-cancelling, 4-way flash, rugged assembly that uses screws to firmly attach wires, built-in audible beep, and works out of the box with either 6V or 12V. I chose their toggle option and added two 6V LEDs from Amazon that I mounted on a small SS plate attached to the dash on the left side. All wiring except toggle hidden behind gas tank so installation is clean/out of sight. I quickly became used to flicking the toggle, and especially enjoy the convenience of the self-cancelling feature.
