well i really want these gauges for the boost project, my question is what type of bulb is in them for illumination? is it similar to the ones in the autometers that you can change the bulb wrap for the color you want, i really want either these or the defi d-series (because they match the em1 stock gauges ) BUT the boost gauge is discontinued and i'm not sure if they will still be around when i'm shopping, thank in advance
