I have limited experence with electronics. I got my Ham technition licence as a kid, but stopped using it a couple years ago, and now I forgot everything. Nevertheless, I bought a beeter Saab, and now I'm trying to find some simple things to do to it. The high beam controller sounds neat, and could be fun to play with. A couple questions though.. Why 2 reays? With my limited understanding I see the SPST relay is just a switch for the SPDT relay. Why have this? Why even have this circuit deal with the low beams at all? Also, the only resister I could find is a 5.1K ohm 1/4 watt, will this work? The only thing I could find to use as the "eye" for the circuit is something called a resistive photo sensor.
