for fun look at these bulbs.

they are essentially the same diameter and length. they do not have the same flange on.
but they are only $1.29 in cool white.
you might go buy a regular ge336 or ge 386 that these are exact replacements for and see if they fit.
i have seen that some guys have used them in gauges ok where a ge330 was. but you will have to determine if the flange is needed or not.
i have also discovered that in my quest for the perfect cheap led light that i spend wayy too much time and with the money i spend experimenting sometimes i could have bought the more expensive one with. so you have to decide if you like the quest of searching or just want them that you know will work. i dig the quest part so spend alot of time doing the searching and experimenting.
i have ordered now about ten different led lamps for the newell to experiment with in different places. different number of LED's., different brightness, different physical sizes, colors etc.
darlene and i ONLY like the cool white (about 6000k color temp). the warm light is too yellow for us.
in fact this morning i was playing with G4 led's that i got yesterday from china (takes weeks to get them, but they are cheaper by far) to replace the 10 and 20w halogen g4 bulbs that are EVERYWHERE in the ceiling of my 02.
as i have posted elsewhere i replaced essentially ALL my interior lights in my 90 with LED's. awesome lighting.
have fun searching,
