LED strips for Brake Light '01 Spirit vt750dc

Alpena 8" LED strip 12v at 0.08 Amps

I know you guys might not like this, but the person who owned them before me had them on and I liked them. But he had them right on the fender and some were burnt out so I took it off. I was gonna make a bracket for just UNDER the rear fender (or to the side mount license plate) so they are straight and people can see them brightly.
My question is how do I wire them up I didn't think I would use them again and he had resistors n stuff, but they are not wired anymore. so not sure how to wire it back up. He had it so when you hit the brake they brighten up and when you let off the brake they would dim so look like a running light.

I have no brake light and tried a couple but can't find one I like it fit, then found these I think they look great.

Instructions says it needs 12v power source capable of 0.08 amps. the reason they light now cuz it came with a switch but it says to cut that off and store the little battery pack for something I just need the wiring.

If anyone knows how to wire this up please help so I can get this on the road and drive.

I bought some similar and they had 3 wires, for running and brake light. I just used the brake light portion and hooked it directly to the brake light wires in the rear. I also added a modulator so they blink for a few seconds and then go steady bright. They are just above my brake light assembly on my home-made luggage rack. Just wire directly - with out the switch. Easier that way.

Hook it to the green/yellow brake, and green ground wires.

I figured about I need 150-200 ohm resistor, and 2 - 1 amp diodes. Or run dual circuit element from the led strips and then hook it up to the stock wiring.

The ones I have run straight off the 12 volt battery power off the lights. Since yours say 12 volts source I think you don't need resistors. Unless the instructions say so. Most 12 volt LED have the resistors built onto the flexible backing board they are surface mounted to.

"Instructions says it needs 12v power source capable of 0.08 amps."

Does it mention what that box is for?

The box is just a little battery cuz there is a "try me" button on the box. I have to cut it off and just use the wires. But I found out I need two 1 amp diodes, and a 150-200 ohm resistor. The resistor will dim the led strips until I hit the brakes and they will light up. So I need to run 3 wires. Then I got a ground, brake light, and running light. But I'm having an itch of a time finding diodes and resistors in Moncton,NB (Canada)

Instructions don't say I need diodes or resistors. But I want the running light and brake light to work. And for the led to go DIM and when I hit the brake they go bright I need the diodes and resistor

I have made some dual intensity turn/running lights. If you feel comfortable taking things apart you can see if some old electronics have diodes and resistors that will work or you can order some eBay

How many wires do you have coming off the LED strip?

Hey there are just 2 wires coming off LED strip just ground and 12v I'm guesssing? That's why I need a 1 out to 2 wire. Then put a diode on each and a resistor on the running light cuz that will dim it. Should work I hope.

Not sure how well dimming will work with an LED. They only work on about 3 volts anyway so lowering the voltage too far (say 2 volts) and it will just go out. Needs more research.
