Hey guys got another one for everyone. I need to make a circuit that is hooked up to the ignition of a vehicle or boat that will turn on 3 LED's for 2 to 3 seconds, then off, as a test of the LEDS. i.e. Low fuel level and temperature high LED. Turn ign to the run position; the LEDs turn on for 2 to 3 seconds then off again. Thanks alot! I have been searching for hours and can't find anything automatic. Everything is "push a push button to test them." I just want to be able to turn the ignition to run and have them do a self check (like in our cars and trucks).
