Quoted from wayout440:I just can't do LEDs behind an EM backglass. They never have the same warmth or spread as incandescent. Color matched inserts and retro or warm white bulbs for everything else are ok to me.
If you use the same warm LEDs they can look pretty good. The frosted ones work well behind the bg.

BG with LEDs (game title is backed by several blinkers, pic is caught in random mid-blink)
HOLY SHIT AND THERE ARE COLOR ONES IN THERE!!!
