It is against the law to change the lighting of a motor vehicle. Especially here in Canada it is very illegal to have a blue light that is reserved for snowplows even in summer.

If you don't want to use a micro it can be done with a potentiometer, a triangle wave generator, and a comparator. The wiper of the pot is fed to one input of the comparator and the triangle wave to the other input. Some type of feedback resistor is needed for hysteresis. The output is a PWM signal where the frequency is the same as the triangle wave and the duty cycle is proportional to the pot. Google it.
 
that project is perfect,but instead of 3 watt LEDs i want to use 6 RGB leds per headlight =12 total(Think 5mm will do thejob or 3mm)OR two 1 watt RGB leds per headlight=4 in total.
