I have some JDM blue bulb caps in my climate control unit & clock display that are relatively whiter than OEM blue bulb caps.
But one of these lights recently went out so I decided to upgrade the rest of them to white LEDs, finally after all lol. Purchased some 6000K LEDs from VLEDS(.)com. I needed three T5 Neo wedge LEDs and also three T4 Neo wedge LEDs to swap out all lights in the C.C. unit.
I also upgraded the clock display light as well as the following buttons with T3 neo wedge LEDs:
TCS button -- one T3
Cruise control button -- one T3 (there was also one more T3 section for that green light I but I forgot abt it lol)
Sunroof button -- two T3's
All of these 6000K white LEDs would light up a little bluish, like my gage cluster, because I haven't removed the OEM blue stuff like my CC unit.
Hence, I was wondering how can these other buttons be "blue-free" as well. I played around with the switch, and started to pull out the button part of it, b/c it was sliding in 'n out like it was a different piece by itself. I added more sudden force to remove the button, as if I was prying it off, and then it just simply popped right out lol. When I looked at the back of the button, there was a tiny blue paint that was covering the letters. I was thinking about scratching it off, or use some alcohol solution to remove it, but it seemed like the whole letterings would also come off. If I remove these blue paints, these things might become nothing but brightly white buttons that won't say anything on them,, so I kept them in the way they're. At least they match with my gage cluster for now.
