Does anyone have pictures of LED's in their gauges as opposed to different color regular bulbs ?

I want to do this mod but was wondering if you could use LED's which are brighter or if you needed regular bulbs which illuminate wider ?

And if I do need the wider illumination, has anyone used the inverted cone LED's I see on eBay ?

I have a 97 SE so the 194's should work. I need 6 bulbs, right ?

Thanks everyone for your time and any info you might provide.
