Dash LED lights

[Dova]

I've read several threads on here about LED's in your dash. I want to change my factory bulbs over to LED's to be brighter. I will be painting the inside of my gauges too to make it all brighter. Here are some bulbs that I found; http://www.ebay.com/itm/380556467425...84.m1438.l2648
What do you guys think about these? Are there better ones than that. I'm not too savvy with LED's. I've read the light distribution from SMD LED's are better. Thoughts on the subject? If you prefer others which one's? With links would be greatly appreciated. Pics of course are always welcomed. And how many green, red and amber replacements would you need? Thanks in advance. They will be going into a 1970 C20. Replacing the gauge cluster with a tach dash gauge cluster.
