I've always wanted to do all of my guages/dash in blue, but I've heard that due to the stock green bulbs, it always turns out more of a turquoise.
the only thing with getting new bulbs is you have to be really good a soldering or you can mess up the circuit boards.
there is no cover then that would make a green bulb look blue? Like, put a purple cover over green? I dunno. There is physics involved here.
there's a whole thread on NASIOC about it. Get wide-angle LEDs and scrape the green film off the back of the cluster.
there are different colored "condoms" you can get for the bulbs. The 06+ STi and I would amagine 06+ wrx hvac controls are led so the "colored condums" will not work.
no problem guys just trying to help. i am only a couple months away from getting mine. I CAN NOT WAIT!!!!
