   Hi,   
   I'd like to try and build a brake light flasher circuit for a motorcycle (12V).   
   Brake light should flash 3-5 times then remain on (solid red).   
   I'm new to electronics so not everything is clear to me. Is it possible to   
   build such a circuit and remain in 12V "domain" or is it necessary to step   
   down to 5V to power an IC (a counter with a clock, for example) ?   
   I'd like to use a 12V LED bulb (e.g. Philips Ultinon R1157), how would I go   
   about starting a design for a circuit using that bulb?   
   I'd appreciate any constructive help in the matter.   
   Best,   
      
   Joe
