Good info. Thanks for sharing. Keep in mind that ebay links will decay and it may be better to just type the brand/model of the bulb used. Amazon links usually just show "no longer available", but ebay's tend to die entirely.
I've used Sylvania blue LED's in my dash previously, and was quite satisfied with the result. I can only imagine their white LED's are even brighter. They looked similar to the Phillips ones you posted the link to.
I'm currently using some Chinese-made LED's because I wanted to use purple fog/turn/horn lights--and purple LED's are still like hen's teeth. There's a significant sacrifice to brightness with purple--and the high-end companies don't seem to offer this color...at least yet.
I have these in my front turns at present, and they are quite a bit brighter than the 194 style purple bulbs, and are well suited for the task. You WILL have to replace the stock blinker module with an aftermarket one for LED use--unless you like strobe-fast blinkers.

Keep in mind that I have smoked, clear lenses on my turns. I would love to find some clear side marker lamp lenses so that I could replace the amber with purple there also.
Oddly, the bulb that I have in the climate control and shifter is SIGNIFICANTLY brighter than the ones behind the instrument cluster.

The bulbs I have in the dash are the 2-stack varieties of these:

I had a 1-stack variety, but they were lackluster. I still have the 1-stack kind in my license plate and the light quality is sub-par. The 3-stack kind are used in the fog lamps and i believe the horns as well.

p.s.
Cree are supposed to be REALLY good LED's. I have these currently installed--replacing my "brite-*** LED's" which failed in <2 years.
