I have not tried to install the hvac or guage bulbs from superbrightleds.com, but the ones from their you can order, I only get discount on those by quantity. As for the 3mm and 5mm leds, I can do all that, also, I found the place i get LEDs from sells resistors, which i can sell those to you and far cheaper then you can get them at the store, 2.50 for every 50 pack. If you want them bright, go with 330 ohm, but if you want them dimmer, go with the 440 ohm. I have the 330 ohm, and They are perfect to me.
