I've played with the different combinations of colors and found using the same color of LED with the lens works best.. The white LEDs seemed to make the lens color funky in my opinon.. The white LED with red lens, when lit would produce kind of a purple color.. Was not to my taste. The white LED with yellow lens would just wash out the color so much it was butt ugly.
The equilizers are an old tech way of taking care of the flasher prob.. Go with the new electronic flashers. You won't "save" any power using the equilizers per se, because the equilizers draw the same amount of power as the regular bulbs.
The tower LED replacements I found solve the viewing angle problems.
