We spotted this trick system developed by Shimano, Garmin, and Trek. All three components: the lights made by Trek, the computer made by Garmin, and the Di2 system made by Shimano work together to form a lighting system controlled by the Dura-Ace levers.
With a customizable layout, the setup we checked out uses a button located under the right-side hood that turned both the headlight and tail light on, while the left side cycles between two modes: flashing high-vis mode for daytime riding and continues for nighttime riding. Another trick feature of the system is being able to scroll though the different pages on the Garmin via the same two buttons. Simply hold the button down on whichever direction you’d like to flip through. The lights also have an integrated ambient light sensor that automically adjusts the brightness of the light. The future is here. This system is available on select Trek bikes only.
