Bicygnals are a brand of combination wireless turn signals and bike lights both front and back.
The problem come in when vibration effects the units either front, back or both.
Since my front unit is "bobble" mounted it affords the "Waggle" necessary to keep on working but the rear unit is hard mounted and fails to continue to signal even after a short distance on rough roads at MaB speeds.
This is the photos of the effort to combine both units electronics into the front unit and to make the rear unit a "dumb" LED unit that shouldn't quit working with road vibration and engine and or lights static noise on the RF.
If these two cannot communicate being just an inch away then there is no hope and so we shall see.
