Re: Headlight LED Dimmer
Look at it again, in your drawing the dimmer is always powered, plus and minus, no matter what position.
The one I posted the dimmer only gets negative when in high beam mode. The positive is removed from the entire circuit when Power is off. I like switching the positive side off since a lot of devices have common negative. |

Re: Headlight LED Dimmer
I'll look at it again. If you solved my dilemma, I thank you.
As I said, I normally switch both + and -, just 'cause I'm wired that way. This is a compromise, which I can fix with a relay, but unlike most engineers, I don't believe, "if it ain't broke, it just needs more features". Even though I have dozens of industrial relays, that's just another point of failure. Thanks |

Re: Headlight LED Dimmer
OK, your diagram should work, assuming the dimmer doesn't fry with power feeding the output. Heck, it cost less than $4 including shipping, so I'll give it a try.

Re: Headlight LED Dimmer
I'll swap the top and bottom negative side, as I want up to be bright and down to be dim. Switch terminals are opposite from the toggle position, as I mentioned, however, you solved my brain freeze problem.
Thanks |

Re: Headlight LED Dimmer
Just as another option.. How bout this ?
Center is 12 volt + both sides Right side is tails, up and down are full power. Left side, toggle down will give full power, toggle up will get power through the dimmer. |

Re: Headlight LED Dimmer
That will not work, according to the OP, the dimmer controls the negative side of the lights. The dimmer shares a single positive for in and out.

Re: Headlight LED Dimmer
I like Sergio's scheme best. Dunno about EEs who can't read my hieroglyphics.

Re: Headlight LED Dimmer
I'll take a closer look this afternoon. You don't show dimmer output. It has two input and two output wires, and + is internally connected on the I and O.

Re: Headlight LED Dimmer
Not sure if I have seen that kind of dimmer but sounds like + just passes through. Maybe forget those connections and try just the - side.
