LED day and night light intensity and color?

I plan to add some LED stripes to my motorcycle which will function as (additional) rear light, break light, turn signal, and maybe more.

The LED stripes which I use have 144 5050 LED per meter and 100% ON they are very bright.

I guess at daytime 100% red is good for the break light and probably 100% yellow is good for the turn signals. But I guess at night time this is too bright.

Obviously I can test this day and night in the sun and on a cloudy day etc. but probably other people did this already.

What is your experience with the brightness under these conditions? Is i.e. 50% brightness at night a reasonable value? Or should it be more or less?
And how about the color? Does it make sense to make i.e. the turn signals at night a little more like orange?

Please let me worry about the legal situation. I live in Thailand and I have to follow Thai laws. They are likely different than in many other countries in this world so legal advise what is allowed or not will likely be different here.

LEDs are harder to see in the daylight.
