I bought some sidemarkers off a fellow CEG'er a while back and I was going to put them on until I saw I needed a resistor and diode for each side for the light setup I wanted (from the How-To). I went to Radio Shack, RS Electronics (Schoolcraft and Stark) and Murry's, and none of them had anything close to what I needed. So where did you guys with the sidemarkers get the required resistors/diodes from? The how-to says 30 Ohm 20 Watt resistors and 3 Amp 15+ Volt Rectifying Diodes are needed. Thanks!
