avoiding using relays??

When I first read the link I thought cool, someone is going to wire all of the high current stuff up through some Triacs (basically a solid state relay just doesn't go click click). Then I continued reading and visions of smoke curls from the dash shook me into reality. Like the poll says don't do it. Every wonder why old head light switches and heater blower switches were thing that seemed to break. High current causes heat in any connection or switch that is not absolutely at or near zero ohms. Lets assume for a moment that you are running standard sealed beam lights. High beam is 65 Watts and low beam is 50. At 13 volts that is 5 amps per side of a total of 10 amps through the switch. The is either 2 runs of 18 gauge wire (one to each light) or one run of 14 with a y connector feeding each light. Now I know your thinking 10 amps, a lot of switches will handle that and you would be right. But let that switch get just a little carbon build up and it then becomes a resistor that is having to dissipate the heat. The more it disapates the more likely it is build more carbon, and so on and so on. Just in case you're thinking that 65 watts doesn't get that hot, reach up and unscrew one of your 50 lamps at home. One last note, the above wire sizes have no safety margin built in. Remember the longer the wire the higher the internal resistance becomes and the less bright your light will be. This is the long version advising against doing it. Enjoy your car for a long time to come.
