While at the BMW MOA 50th Rally in Roswell, VA., I purchased a set of the Demali T3 Switchback Turn Signal lights. I paid for them there at the Rally and they shipped them out to me after the Rally. I received them within 4 days. These were much easier to install than I had anticipated.
They are very bright and I highly recommend putting these on your bike if you are worried about distracted motorist running into you while you are stopped or attempting to stop or turn.
