For reference, I'm using an Edge 1030 (software version 13.75) with a Trek Commuter Pro RT headlight and Trek RT Flare tailight. Both of these headlights can successfully connect to my Edge 1030, and can even be controlled via the Edge 1030 interface (off, flash, solid, etc.).
On my system, the "Light Mode" is set to "Individual", and the lights turn on when I start an activity (Timer Start). All as expected. However, about ~2 minutes into my ride, both lights shut off unprompted and do not turn back on. This requires me to turn them back on in the control widget on the Edge 1030 manually.
Attempts to fix the problem, all unsuccessful:
- Unpairing, resetting to factory settings, and repairing the headlight and taillight
- Manually turning the lights on in the light control widget ("solid") prior to starting the ride.
There are a number of similar threads reporting this issue and none of them have been answered definitively. This is a potentially dangerous situation that can lead to an accident.
