Just found this thread and have to say that this information is awesome! I have been contemplating switching most of my bulbs over to LED's since getting LED tail lights, and now after reading all of this, I am determined to do it. Now I just need to figure out exactly which lights to use for each area. I dont think I am going to paint the inner area of my gauge assembly blue (although I have to admit, thats looks amazing) so I guess I need to know which LED's work best for stock use. I also will be looking at replacing my courtesy lights, licence plate lamp, tach light, and front turn signals.

They are a bit more money, but the lack of heat, less energy draw, and longer life more than make up for it.

Thanks for taking the time to post all of your tests and the information on the bulbs you used. All of it is great info!
