I had the parts, but bought at Radio Shack, about $3.00

These Transistors need a heat sink to cool them down. They will be more steady when kept cool. Hope they burn out open and not closed. Open means no voltage, closed means a full 12 Volts hitting your gages. I'd just use a dielectric glue to glue an alumumn heat sinc on the back. DaveJ
