So the part numbers are really obscure. On their web site (superbrightleds.com) you can query "194 LED bulb - 4LED - miniature wedge base"
They have 4 LEDs on the end of the bulb. You need to use the plastic holder on the original bulbs. The old bulbs just pull out and the new ones push in.
I also had BA9 bulbs in my gauges that are wired to the instrument panel fuse so that they dim with the dash lights. I got "BA9s LED bulbs" I got all the bulbs in cool white (there are alternatives) The BA9 bulbs have the same 4 LEDs on the end of the bulb, so they all put out the same amount of light. Before I had an oil pressure gauge that out-shined all the rest of the lights, now they all look the same.
They all dim uniformly and seem to have no problems
