Not sure but summit sells these translucent covers for 194 style push in bulbs that change the colors for back lit gauges.
They have red , blue and green.
Would work in a pinch to make all the same.
They say it doesn't, but, a Crackedback headlight harness, not available from him for some time, illness, sure brightened my dash lights up. Leds sure didn't do it either.
It's a wiring harness with relays and such for your headlights, it bypasses the bulkhead connector. There are other versions of it, but Crackedback has health issues and hasn't been offering his version. Install is in the sticky.
