When I went hunting mA, I swapped all bulbs for LEDs.
I wanted red to keep from killing my night vision, and it is pretty hard to read at night, but it doesn't affect night vision at all. To get even lighting, the bottom bulb under the odometer needed to be a bit brighter.
From SuperBright, I got:
If I were to do it again, I would probably go with green, white, or amber, because the red just doesn't work well with the stock coloring of the gauges.
I also did the indicator bulbs with the same WLED-G-120 (Yep went green all the way across, even the high beam indicator), and that is about perfect for stock replacements. Since they are non polarized, even the turn signal indicator work just fine.
