Remove your turn signal bulb in the odometer.

What would removing the od bulb do? What magic is this lol?

On a lot of cheap Chinese LED lights you'll see red/black/white wires and white is ground.
On a bike with all incandescent bulbs, including the dash indicator, the bulb in the dash sees voltage flow in both directions depending on which blinker is active, left or right. You have to install two diodes to make a common dash bulb work with LED turn signals. |

I don't know if this applies to the Magician, but the headlights on my scooter operate on AC.
There is a separate coil on the stator |

What scooter? I've never seen that before. My magician was all DC 12v. When swapping out all my lights for led lights I had to remove my turn signal bulb in my odometer because it would cause a short in the turn signals since it would transmit power. LEDs use much lower power and also have lower resistance so it could allow power flow when I didn't want it. Regular bulbs wouldn't react to the low power flow since they need significantly more power but my LED lights did. Apply 12v to each of your LED things on your bike to verify they work, then double check your wiring. Either way you will need to remove that bulb or your lights won't work properly. An LED blinker relay is needed to make them turn on though. A normal relay won't react to the low current of LEDs properly. |

It's a Dong Fang with a 150cc GY6 engine
The Magician may be different Also, LED's have a higher resistance which means they consume less power Voltage=I*R Power = I*Voltage |

Dude, what? LEDs have more resistance at rest, although comparing them to incandescent isn't really apples to apples. Basically, at rest or low current an LED will appear to have more resistance, but a lit bulb will have significantly higher resistance. When metal heats up it's resistance goes up. Here is a quote for you. "The typical cold resistance of a 100 W incandescent lamp is about 9.5 ohms. If that resistance stayed the same with 120 V applied, Ohm's Law tells us that the bulb would draw about 12.5 amps and dissipate about 1,500 watts. That doesn't happen of course, and that's because as the filament heats up, its resistance increases as well. It turns out that at 120 V, the resistance is about 144 ohms, 15 times the cold resistance. The resulting current is 0.83 amps, and the power dissipation is the advertised 100 W." It explains it a bit more. More resistance != less power usage. You're confusing how power works. I tried to lookup dong fang 150cc scooters and all I found were 12v bulbs. Are you sure it is an AC bulb? I've never heard of or seen any AC bulbs on scooters. I saw some aliexpress links for led flashers, here is one you can get quickly. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 Those fit the magician. I'm using one. You do not need separate circuits. When I installed my LEDs I did not have to rewire anything. I just snipped the old wires from the incandescents and hooked them up to the LEDs. With an LED flasher and removing the bulb in my odometer they worked fine. They work currently. There are NO relays that I had to replace, I didn't change anything else. |
