Just came across these while having a browse ,

They are green 3mm 500mcd leds , although they are a lower mcd rating , they have a light output angle of 70 degrees ! , thats huge compared to the blue led's i have come across , you'de probably find your displays would be pretty much as bright due to the high angle light output , it would also help remove hotspots even more / i barely have them now / but imo with these i recon you would have none at all.
Just an option anyway if you don't want blue .... Im thinking about green / just to break it up a bit from the blue dash lights and cfp lights a bit , etc etc ( i want all the lcd's a different colour really ) . But im still deciding due to the old saying "blue & green should never be seen " , or the "red & green should never be seen" scenario.
These 3mm green 500mcd led's are only 1.7v @ 30mA , so if you want to use these instead , use 3 of these leds and a 98ohm resistor wired in serial as above in the document instead . ( or 100ohm max / or lower down to 80 ohm minimum , i based this off 14v , so you have a bit of play safely either way ) .
These 3mm green 500mcd leds can handle up to 2.
4v @ 160mA 'each' before frying , thus allowing you to go as low as a 80 ohm resistor safely with 3 wired in serial, try to stick to around a 100 ohm though or just below if you want to use these green leds instead / and to have them running around there standard voltage and milliamp rating .
You could actualy go to as low as a 15omh resistor with the 3 wired in serial but you would be pushing the leds on the verge of frying. Even anything below 80ohm sorta is starting to push the leds past their limit , possibly causing a shorter led life or fyred leds.
cheers .
