thank you for answering. i can give more detail. i need a relay or bulb 12v automotive to be normally off with the ignition off. as soon a the ignition is on or when car is started, i need a bulb to light on and be adustable for the time it remains on once the ignition in on. in other words, turn ignition on, but dont start. if you look at a dashoard, the "idiot lites" com? i am no electronics engineer. i can read a schematic, hook up the components, but, i dont know what a FET is or how it works. bare basics, thats it. thank you again , sir for responding
