Changing led colors using pressure switch.
OK just to be up front i have no idea on how to do this so i would need the full story. i do know how to read schematics and can solder and most of the basic stuff. what i am looking to do is install led lights under my hood of my car in each of the snorkels that receive air from the outside. basically you can see down the snorkels to the engine. i want to install the leds so that when driving around under a no boost condition the lights would be green then when the engine get 5 psi of boost they turn yellow and then 8+ psi the glow red but with the higher the boost the brighter it gets so lets say at 10 psi the intensity gets brighter. like i had said i really have no idea how to even start this or what parts i am going to need. i can give you what ever info you might like i know i will be supplying approx 13.2 volts as system is running but it is in a vehicle so the alternator does fluctuate depending on need of system.
if this doesn't sound fees-able please let me know and i can scrap the whole idea. it just sounded like a cool idea thank you
