I have seen the different people's LED swaps, however, I have only seen it done on the regular HVAC controls. I have a JDM B4 with the digital controls, I replaced the 5 bulbs with blue LEDs, but the digital display is still in green and the buttons all light up blue. My clock and odometer on my gauge cluster do not have bulbs that can be replaced like the ones I have seen on here, all I did was replace the 4 bulbs with blue LEDs and the clock and odometer changed to blue also. I'm doubting that I'll be able to change the color of the display, I am just hoping that someone on here might have changed it.
