Hi,
I made a brake light flasher for my car using a 555 and a 12v relay to blink two pairs of bulbs alternatively. It works fine but makes a lot of noise each time I step on the brake and it is quite irritating to hear that tic-tic at a traffic signal for a long time. So I designed a solid state circuit of the same. I managed to design the +ve side driver but I have no idea what to do for the -ve side to make it like N/c and N/o of a relay and blink the lights alternatively. Each pair would have a power consumption of 30W(max) I guess.How would I go on for the other side??
