Improve those dash lights

Which bulb are you guys using? I see 1led , 3 led, 5led, 15 led etc...units available so which are you guys using ? Will a 90 to 120 degree spread be enough ?

I also see 1156 and 1157 units are available as well , is anybody using them now ?
The small dash bulbs I used were only 1 led I think. I got them at O'Reilly's. They didn't say anything about multiple led's and being their so small I doubt they were more than one. I tried some of the 1157 LED's in my tail lights and they didn't produce any more light than the regular 1157's but I just picked them up at Walmart and there's a bunch of different ones so maybe some others might work better.
