I have 2 LED lights, designed for 12V, a 12V power supply, and 2 switches. I want one switch to turn on both lights, and the other switch to turn on just one. I have a lot of electrical knowledge, but not so much in electronics. To me the diagram below would be how I wire it. If this would work, all I need is a diode, but I know nothing of them. Could somone tell me what kind and or where I could get one for this?
A silicone diode that is good for up to 1 amp. This one probably take drops 0.7 volts leaving 11.3 for the led (I assume these are rated at 12volts?). http://www.radioshack.com/product/index.jsp?productId=2036269&CAWELAID=107591270
