LED dash lights

[Jeepman85]

I have a 85 CJ7 with stock gauges. I'm wanting to change up the color and be able to see them better at night. I hear there are a few different bulbs that were used ( just different lengths I think?). The led's I'm looking at are equivalent BA9s and are 30mm in length. The question I have is, will this length of bulb work for all the separate sockets in the dash (speedo cluster, volts, oil)?

Thanks in advance!

If I remember right they are all the same except for the square function indicators. Speedo, volt, oil, tach, clock should be the same.
