Custom LED control module for vehicle
I assume you are new to electronics, so I would just point out probably the easiest way for you to make something like this:  


Arduino board - easy for newbies to program and implement some simple projects like yours. 
LEDs and resistors.
Some MOSFETs, because you can't drive more than 40mA from microcontroller
Power supply - probably you can run it with your car 12V battery, but anyway you should sit and think about current, voltages and other stuff.


And of course the knowledge how to use it. Just google about LED driving with Arduino, there are million articles about it.

You could of course do it all analog using different analog ICs, but if you don't have much experience with it it probably will take more time.
