I had changed my tails to switchbacks and I really like the look, although I have always been slightly concerned that there isn't enough difference when the brake light comes on.
I added a back-off box...just an inline flasher that gave the brake light a 3 pulse then steady that repeated about every 3 seconds.
I had always liked the look of the small led surface mount light head in place of the rear reflector. So I found THIS on evilbay for $20.
It is plenty cheap enough for sure. Shipping was extremely fast. Installation was simple as well. I didn't take any pics but it's definitely not bad. I will get a pic or video this evening
