Hello,
I'm developing a project to use on my daily drive car and I came up with a problem concerning the use of some LEDs. Thing is, I have a LPG switch with embedded lights to inform me about the amount of gas remaining. I'm thinking of adding a couple of led (3 green LEDs and 1 RGB) to show me that levels on the odometer. The original switch already provides those LEDs but they are SMD and I can't use them on the odometer. What I'm thinking off is soldering two wires in parallel with the LEDs ( on the switch ) and connect them to an auxiliary circuit that helps me powering up 3 or 5mm LEDs glued to the odometer . My idea is to use the standard 12v used on almost all car circuits and use a voltage regulator (to 5v maybe) and a couple of relays . This way, when the LEDs on the switch light up, i'll have a high level voltage on the relay and it will provide a path for the 5v to light up the 3 or 5mm LEDs . Is this a good apProach or can i use another one?
Thanks,
Diogo Ribeiro
