Bulbs for instrument panel indicator lights

Does anyone know what bulbs are used for the instrument panel indicator lights on a 2001 Tacoma? These are the lights below the four instrument cluster lights that everyone replaces to change the color of the gauges. The bulbs light up things like the check engine and low oil pressure indicator lights.

 

I have a 2004 and when I replaced the instrument cluster lamps they were 194 or you can use 168. The CEL, low oil light and low fuel etc. they’re a lot smaller than the cluster lamps.
