The military uses red and green bulbs for nighttime operations. Here are the LED’s on on a HMMWV dash.I'm not completely sold on going all in with LEDs. I started down that rabbit hole and I may revert back. I like my indicator LEDs, turn and high beam, but the guage cluster lights are a bit too bright. Its distracting while driving in complete darkness. They do not dim and that's my problem with them. I love the color options. I need to playground and see if I can shade the lumens a bit.
Yeah, I'm using red LEDs for my gauge cluster lights. They're still too bright for my liking.
Actually they start off blue. Then transition to the later colors.
