Hey Everyone,
I am building a PCB for flashing headlights on my freinds vehicle (he is a volunteer fireman) I am using a basic 555 timer with a 1Kuf capacitor and a 300 Ohm resistor for the flash timing. I utilize the high and low states of the 555 and thats o.k when using LED's because the polarity can be reversed. Now I want to use (2) 555's and switch the headlight lamps (wig-wag) ... I don't think a PCB miniature relay could switch that fast, and even if it could it would'nt last very long. Now I am hoping someone can help me find an IC or other component that is capable of switching heavy lamp loads very fast and can do it by the 555 pulse I send to it. All suggestions appreciated very much. Jim P.S I pondered the idea of having enough 555's in paralell to handle the load but that would be a heck of a lot of timers because I think they are maxed at 200ma.....
