It seems to me that it is not well explained. because I can't understand I would like you to verify your esteemed answer Julio and carry it out imaginary or on paper, as it does not come out.
Hello July a favor. If you could give me a connection detail. for example. The positive cable goes to the motorcycle focus. (only one cable) and the other end where it goes? Now the negative is understood to be the issuer. and that the LED is also connected to the positive cable, but where the remaining cable of the bulb goes. Regards.
... positive battery or positive source to the bulb, cable coming out of the bulb, to the transistor collector ...
Now, thanks. I placed it on a fp1016 and turned the spotlight on the first. They are wrong. and I put it to an fn1016. and did not turn on, but when the led was turned on. result the fp are bad. because there is audio in the aiwa but very low, just like a headset. Regards.
... a positive touch will turn on the bulb, it is possible to stay on in some cases, a negative touch will turn it off ...
