I want to build something that can dim an automotive bulb from 100w from full brightness to just glowing. I will be using a micro controller to do the PWM, but I am not sure where I should look in terms of a simple 12v (14.4v when the engine is running) PWM controller for a resistive load. Any suggestions to get me started. If it's just a few components to source I can easily build on that.
Doing some searching, an IRF530 looks like it could work?

Run a microcontroller PWM to control the mosfet to control the 12v light?
