I like LED's just fine, the frosted cap 44-47 replacements do the job pretty nicely.. I think the #455 replacements are a little lacking because they dont blink fast enough and-or a slightly random speed like the real 455 bulbs do for having the temp actuated reed switch inside (especially the GE's that blink real fast). the fast blinking color changing RGB LED's are pretty cool to play with some places, gives a newer look to something that never had anything like it, as simple as changing a bulb out. just messing around I'd replaced a few bulbs in the backglass, the blinking colored lights play some fun games with the colored painted and letterings, almost like a different colors neon strobing effect, might be worth messin with some. for that, similar LED's with flex heads might be better to play with in the backglass. I swapped in LED's because I got tired of opening the machine every couple weeks (or less) to change a lightbulb that'd burnt out, its much nicer now, but I might swap in some double LED's a couple places where the single frosted domes dont seem to throw light far or bright enough, isnt a big deal, theyre still cheep enough.
