Installed one of these last week, has to be the most bling shift light I've ever seen, three FULLY programable zones, brightness, colour, number of blinks, blink speed, RPM all for THREE zones in the Rev range, all programmed from your smartphone with the HealTech App! I was actually VERY impressed, you can even turn off the zones so only one shift light or run two or all three, even mix RGB colours to make any colour light you like! You'd be shocked how many features can be packed into one shift light. For example, set a colour for start of shift zone I.e where your Quickshifter kill time is slick, one where it ends and a Rev limiter light in red. Endless... The app screens. The light. WARNING may blind you full whack! Very cool!
OCD the GiPro X has shift light but not like this, the GiPro DS is without Afaik. Blade, very simple power to a switched supply, side light or rear light wire would do, then one wire to the crank position sensor, then fire up and run the app, tap the sync button until the Rev counter matches the one on the bike, then just dial the revs, colour, number of flashes and so on, tap upload and it's done.
