Dr. Peter Terren of Bunbury, Australia, went all out for Christmas a couple of years ago with a Christmas bike with the "world's most powerful bicycle lights."
At around the same brightness as 10 standard car headlights, it is far too bright to be allowed on the road. Peter explains that he has used the latest modern light emitting diode technology. These LEDs are a huge 100 watts each and he uses 18 of them, each with it's own cooling fan. The resulting 100,000 lumens of light power is many times more powerful than any other bike light and is being considered by Guinness World Records. Put another way, it is like having 5000 small LED flashlights on your bike. But hey, there's more! Peter has included coloured LEDs to enable any combination of colours from the front or rear lights.
Not exactly what Santa needs to stealthily sneak into your home on Christmas Eve, but it will for sure spread Christmas cheer -and wake the neighbors! See more pictures at Tesla Down Under. Link -Thanks, Peter!
