i attempted to set up the 13005 based dimmer when i realized that the common collector e.g. an emitter follower setup is not good for current limiting/regulation
you can always make sure your led-s not over loaded by choosing the proper resistors **for max Vcc
but it's likely more reasonable to build your thing up from 2 modules
a dimmer (generating proper waveform for ↓2.↓)
a led switch (controlling the LED-s current) -- would also ensure enough brightness running from battery only**
as your next concern may turn out the LED-s not holding up
Resister(the one connected between timer out to transistor base) gets warmer, but not so hot. I haven't driven the car more than 1 hour straight though, will take it for a long drive and see.
