im looking to get some lights for under my car as well as inside under dash. i have the $$ for the dash now so im looking at the LED from Streetglow. They have 2 diff types of LEDs though ones that come in a strip and ones that come in tubes. Which are better? I want LEDs that wont give off spot light but instead an even light like neons give off. Which ones of the 2 listed will provide this for me? also can i join the interior LEDs with the underbody LEDs once i get those to work at once with one switch? i will also want to join the inside and outside to work at the same time with the music interface once i get those. will i be able to hook both these up to work at once?
