Default Instrument cluster back lights

Wondering if anyone has done a LED upgrade to the guage cluster. I am wanting to change out the lights that illuminate the guages from white to red. Are these 194 bulbs or something different? Any help would be appreciated.

From what I remember the gauges are actually illuminated using UV black lights which cause the gauges to fluoresce. Not backlit by incandescent bulbs.

The originals are incandescent UV bulbs. LED UV bulbs are manufactured. Whether they will have the proper UV light for this application is something I can't say and may vary based on who makes it and in what spectrum range they operate.

PS: The originals are not in the spectrum range that I consider to be "black light", but still UV.

Here is a picture of the original bulbs. The plastic bases are about 1/4 inch in diameter, the black base looks a little larger but have not put the micrometer to it. The left side is white and the right side is black. They are different size bulbs with different part numbers.

The UV bulbs in my gauges were definitely 2 fluorescent tubes about 4" long, one on each side of the gauge cluster.

^not my car, but I didn't take a pic of mine when I had my dash apart.

the bulbs are for indicator lights (turn, high beams, CEL, etc). the actual gauge faces are front lit with UV

Sorry for misleading anyone on this. I started a post 6 months ago trying to get info on the UV bulbs. Until now no one who posted had a clue or that the ones I bought were correct. It did not make sense that such small bulbs would do the job.
