Good luck, I have an idea in my mind on my bus. Like all older cars, it has an indirect instrument lighting with light bulbs that illuminate the entire speedometer. However, there are plasma dials that glow directly. So that the needles for speedometers, rotary zalometers, fuel meter etc. can be seen, I want to paint the needles with UV light shining varnish and light up with UV LEDs instead of light bulbs. Has anyone already done something like this? Which LEDs would be suitable? How much mW of light output do you need and where do you get LEDs that don’t glow violet, but only emit UV? Thank you Baumi
