The cool thing about that site is they have a brightness scale for all of their bulbs. The 360* bulbs you picked shouldn't leave any dim spots in your gauge.

 

Well I got the "natural white" 5 SMB led bulbs, and they are the same color as the "cool white" 6-led ones I tried for fun. Not too happy about that. So I ordered some "warm white" ones on eBay to try. Might just back to regular bulbs though. The whole purpose of me doing this was to match the color to a speed hut boost gauge I was going to put in the cluster where the trans temp goes. But now I might just put my wideband there instead and not worry about it. Indecisiveness.
