Me and my dad restored an old camaro and retro fitted the guage cluster with leds. We had four left over and they happened to be white wedge 194's. Not unlike these.
I pulled the instrument hood off for the second time. The first time removed it, about a week ago, it came off cleanly. This time two of the clips snapped. Oh well.
Anyway I just swapped the 4 bulbs with LED's and put everything back together. Took 10 minutes.
