I haven't seen them around here but then again, I haven't seen many modded IS's around here. I was thinking about going with hyper white bulbs for my blinkers or at least the silver bulbs to kill the orange effect when they are not in use.
I have sylvania ones. They look like a bubble in the box. They are blue,purple,red,green - and when they blink at night they are different colors at different angles, but the majority of the color is orange.
