Eventually I found a 10k resistor gives a safe light level for night sailing with the white backlight. For dawn/dusk or with a red filter on top then a 3-5k resistor is sufficient. Remember to buy a logarithmic pot. Your eyes work also logarithmic. RE: Screen light too bright - seandepagnier - 2020-01-18 the logarithmic one is a nice, but I"m pretty sure a regular pot would be ok.

There is also a photo resistor to turn the light off if it is not needed. Will the photoresistor still happen? And can the Arduino vary the backlight?
