Great light mod and video!
A couple of things I'm curious about.
1. Why did you make them separate switches? Do you ever want to turn them on and off independently?
2. if there wasn't a fuse for the original light, why do you need one now?
3. Did you have to buy just the right AC - DC converter to match the light specs? How much power is coming out of the blower?
I'm assuming the machine generates 80 or 90 watts of power.
I done this light mod on my Platinum 30 machine first using 35w sealed beams. If I run both lights with the hand warmers the lights will dim slightly. That is why I added 2 switches to the new machine, (even though I went with LED lights I wired it with 2 switches automatically, in the event I needed to power off one of the lights).
Of course the LEDs draw much less than the sealed beams.
Because I added lights, a bridge, and a pair of switches, I thought to be safe and run a 5a in line fuse before the bridge. So if anything shorts out, it is something I did and I won't harm the machine in any way. (even if it did short out I don't know if I can burn something out or not)
So I'm just playing safe with my wiring job and adding a fuse.
The bridge rectifier is a very simple part that converts AC to DC. As long as it's rated for more than you are going to draw, then your going to be safe. The one I installed is rated for 1000 volts at 50A. I'm using 12 volts at 3 amps so I'm safe.
