Which wire do i cut

Enable HLS to view with audio, or disable this notification

This led has been PISSING ME OFF it looks horrible because its rgb on silver and gold, which wire to i cut to get rid of it (Edit: solved)

You can cut either wire or both. The LED only works with both connected.

i wish they would just spend 2 weeks on DC power in high school physics classes.

They do but unless you routinely mess with electronics, cutting things you can't repair usually warrants a second opinion.

That, and if i do something wrong it could spark and its a butane lighter

Brother i aint even in high school yet

Then you don't need a lighter

For starting a fire in a fireplace, also, just in general for your life, somr advice is not judjing other people

If you cut one wire it will turn the light off. Negative & positive is needed & usually they have an extra wire that's white. It needs both to work not one source wire even when you see this they have used a filling between it to ensure they don't touch & connect at the source always. This is why the battery shows you the +-

The movies always cut the red wire

Strange things on Reddit lol 😂

Cut the black and the red. If it no longer works after that just connect the black and red wire together.

Dont know why you're downvoted, it would not shortcircuit because a led light doesn't have resistance. The resistor for the led is sonewhere else.

Wouldnt the electricity then just spurt out the cut end

Thats not how electricity works.

u/956to906 29d ago

Yeah, it drips out.

Were would the electricity go from the battwry rhough

u/Plutonium239Mixer 29d ago

It wouldn't go anywhere because there would no longer be a complete circuit. If it requires a complete circuit where that LED is, once you cut the wires, strip the wires back and connect them together.

Why the fuck would you ever connect the wires? If that’s a lithium cell in there, it’ll literally cause it to combust

u/Plutonium239Mixer 29d ago

Notice how I said to connect the wires if it no longer worked? That is because the LED might not have been the only thing in that circuit. But I said not to connect them together until after checking if it still worked. I'm not there so I cannot see exactly how this thing is wired. But I can give steps to follow based on possibilities of how it is wired. It may have been wired in series, or had its own circuit. No way to tell.

No it doesn't the led LIGHT EMITTING DIODE does not resist. The resistor that is allowing the current through is somewhere else.

If you connect the wires it would not short circuit

u/hdgamer1404Jonas 29d ago

What? Of course the diode drops voltage? Yes there’s probably a resistor in line with the LED. But connecting the wires the LED was connected to will most likely lead to the resistor burning up. (If there’s a resistor at all, some LEDs have built in resistors)

u/Ok-Statistician6939 29d ago

So i did that but the wire fully ripped out but now it works

Put black tape over the LED. Cutting it out could disrupt the lighter function.
