I use Smart Bike Lights 1 and 2. One for 2 lights, two for the next two.
Remember to synchronize each light with its serial number in the program's configurator (as mentioned above) so that the two front lights don't turn on at the same time, and it works perfectly. Regards.
and I forgot, we don't connect the lights via the original built-in Garmin application, only smart bike lights and there are no problems with Bontrager ION or TREK lights
