Well, I've done a little research before posting this (trying to find stuff on ignition ring) and from my understanding the dash is cake on install/removal. The dash I know there are LED wedge based bulbs that fit directly into the old bulb housing (no soldering, just remove, then reinstall). The PODs are probably the easiest, you simply replace stock bulb with a 3mm led and attach a resistor to the negative lead (shorter leg), then re-install the base and your done.
As for dude with the dim LEDs I've read on that too, but all I can find is the fact of high quality LED use, but IDK which brand/company has the best or what ones you've used, but I've seen the best are the W-LED 5LED wedge base #194 from

BTW @ reptile : What color LEDs did you use, are those just straight blue or like some kind of super white?
Either way, I may have to hold of on this for a while, 'cause I'm currently broke but I will post pics with before/after, and state exactly what LEDs I've used and were to get them.
