Simple Oscilator (555?)

Hi i need a simple oscilator designed to alternate on/off 2 x 12 volt(60w) bulbs in a similar fasion to police car front lights.

I think maybe 555 timer is the best way, but i need this interfacing with 12v (60+Watt) circuit with us of mosfet or similar. Would also like to include function so both lights could be on or off together. (maybe this is all better done with simple PIC?)

Would also be interested in actual supply of completed circuits not just design

If interested let me know

While using the 555 makes a simple circuit a PIC could be more interesting. Any PIC that suits your budget for builds. If a PIC is used the following can be implemented. 1. Use of buttons instead presets to vary blink More

I would use a Microchip PIC16F74 microcontroller for the timing. One problem with this project is that the on/off response of an incandescent bulb is slow. The element in an incandescent bulb has to heat up in order to More

Hi. Both solutions have pros and cons. The one with 555 timer: Pros: only hardware, reliability. Cons: hard to modify. PIC solution: Pros: Easy to upgrade, more capabilities. Cons: need to program every chip (if you wa More
