Tongsheng Nightshade ? or VLCD5 Hoodie ? Maybe a niche one, this.
Tried it out this morning at 6.45am. A solution to the problem I have had with my Tongsheng TSDZ2 conversion e-bike's display when riding at night (and I really enjoy riding in the dark - no-one else around, and all you hear is the local widlife).
The VLCD5 display is remarkably big and clear for daylight viewing. But when using it at night - to turn on the front and rear bike lights - the display's backlight that then comes on is so bright, I lose my normal eyesight's darkness accommodation.
Maybe it's the contrast being too much - between the almost pitch black of our our local unlit country roads, and the display shining up at my face like a WW2 searchlight. It's amost uncomfortable, to the point on last Saturday evening I was riding for several miles with one mittened
hand covering the display.
Here's the removable "nightshade".
Seamgrip urethane glue, plastic fabric off-cut (from the base of a modified rack bag that covers the e-bike battery), two strips of double-sided velcro, and two layers of car window tinting film (20% variant). Sharp knife, steel edge and cutting board. Put together over several nights (working on one side at a time, 12 + hours for glue to cure. And 24 hours needed to avoid adhesion where you don't want it. DAHIKT).
Here's the effect.
As I'm not interested in my total distance ridden, or the other icons on the lower part of the display, I've reduced the window of information that shows through the tint to just the top half - power level, speed and battery level. The remote control allows all functions to be used, even though the buttons on the VLCD5 are covered. And when in place, the whole thing gives some protection against mud and rain.
