One of my New Zealand customers has some good YouTube content on good passes from vehicles since he's been using the DS-500.

His comment from YouTube:
"When I upgraded my DiNotte 400R to a DesignShine DS-500 my "Good Passes" (In New Zealand, a very dangerous place for cyclists) went from about 3 per year (yes per year) to 3 per 4 hour ride. The DesignShine takes away any driver's chance of claiming to have not seen you, so they know they had better not hit you! I love this light and would hate to be without it. If you can light up a truck driver's Hi Viz top, you know he has seen you (see below)."

If you have some good on-bike video you'd like to share, this would be a great place to do it.
