those look nice, and are a great price...
its hard to tell from the pix, but if they were too bright, or uneven you could add more series resistance to some to dim them down some.
a normal led draws about 20ma with a 2v across it, so the normal dropping resistor is about 500 ohms., you could add another 500 to dim them down some.
when i redid my indicator lights i used a much larger resistor cuz they were way too bright.
when i get power on mine i just may make that same upgrade you did.
