I also installed the signalminder and I love it! I tried to install the little springs inside the switch and when I opened up the switch housing YIKES! parts flew everywhere, TINY parts, I was lucky to find them all and thought I'd never get it back together. I also installed the tail-blazer which flashes the brake light when you fist apply the brakes, all those flashing lights really get attention . I feel better when I am sitting at a light and I see some giant SUV bearing down on me with the driver chatting on the cell phone, I grab the brake lever and I've got three flashing lights coming on. Sometimes I can actually see them mash the brakes when I do that.
