I went to his shop about 60 miles away. I don't mess with wires or much else so I had him install them.
But they are available many places. Amazon, Ebay... These are Police grade so much better quality and much brighter than most Bike accessory stuff available as far as flashing brake lights go.
5 leds will be too wide to fit in that spot where the reflector is, but you can custom fit it anywhere you would like but personally these 3 leds are very bright and get a lot of attention.
BTW.. Don't even think about using blue lights or you will see more blue lights than the ones on your bike![]()
