Hello,
I am attempting to hack my cars brake lights. There are three bulbs with the below stats that need to switch on and off using the Arduino for prototyping.
Each bulb has two filaments and 4 contacts:
12.8V -- 2.23A
14V -- 0.48A
I assume that one rail is the always on when the headlights are on and the other is the brighter one that kicks in when the brake is pressed or the blinker is on.
So I'm going to have to make some sort of power supply to drop the 12V car system to 5V for the ardy. I'm pretty sure I can figure that out. And I know I'm going to have to use transistors to flick these bulbs on and off.
Something I've never had to do before though is find the right transistor for a specific application. I did some searching and located the following...

I just want some of you uber brains out there to check my work... Did I find the correct one here?
Thanks for your help in advance,
