Ok, have installed the turn signal cancellation unit called Signalminder from Kisan Technologies.
Originaly ordered the model SM- 3 but it did not fit my plug. Called and they said to try the SM-3M which did fit. I think Grambo asked about LEDS - it will work with them. Pretty straigtforward installation as you just take out the original turn signal relay and plug in the new unit. Its programable for three different settings: 8, 16, or 24 seconds after which it shuts off the turn signals. It has an extra feature where you can wire into the stop light and it will stop the countdown while you are waiting at a traffic light with the brake on. It will continue the countdown after you release the brake.
I tried it today for the first time and am very pleased with it. I think it has given me a leg up on a safer ride. Their address is: www.kisantech.com
