This is a long one, was even a longer day. Am towing my camper to haspin. Last year I used a 24v bulb in my magnetic towing light set. Had to rewire it because the 24v bulb elements are reversed from the 12v bulb.
I lost the 24v bulbs, and at 11.00 a piece from napa, they are not cheap. In a time crunch, so didn't want to order anything and have to wait. On the web, a couple of places offer them for 2.00 and less. Plus I would have to buy a second magnetic light set, that way I don't have to rewire my only set every time I used it on the deuce. (another 50 bucks.. GRRRR.)
I am not very familiar with electronics, so I called a couple of guys. Thought about adding a second set of lights in series to reduce the voltage, but the bulbs share grounds. Would end up with about 8 lights to get it to work!
So we ended up with some IC voltage regulators. They are good to 5 amps, and reduce voltages up to 30 volts to 12v. Expensive at 25 a piece. Bought 3, one for tail lights, one for left turn, and one for right turn. They ground through the case. Part # NTE933.
Made up a small box for them, so I could seal it. This is a first for me, so may not be to standard wiring! And you can see why I need a trailer plug.
Wired it up, and OMG, it works! Only thing is on hazard lights, only one side blinks. Think it needs a diode somewhere for that. Tail and blinkers work, haven't tried brake yet.
First pic is of plug, second one is lights, Third one I tried to show the back of the regulators, and wiring. Fourth one is the box I used. Still need to seal it up, and add cover over the regulators.
Feel free to point out what may need fixed yet, as I said, I am no expert at this.

Had some really goofy things happing, like touching a wire that wasn't connected to anything, but ran with the other wires, and having a light quit. Talk about weird. Turns out we had to add some capacitors to the wiring after the voltage regulators. They were making noise, and would pick it up from the wires over the 20 run of wire. Once those were in, everything worked great. Still need to finish fabing the box up, and get it water tight.
