LED Lights

Ordered 3 45LED lights from superbright. two worked in my kitchen light and one didn't work in the couch light... I sent the one back and this is what they said.

What the heck are they talking about?

"Hello,
We received your return today, and wanted to inform you that the bulb you sent back is working for us. I believe the reason the bulb is not working for you is because it is a polarized bulb. Ways to fix it would be to add a resistor to the bulb, or buy a non polarized bulb.
Would you like us to send your bulb back, or refund the cost of the bulb so you can purchase a non polarized bulb? Please advise to expedite your return."

Did you try that light that didn't work in one of the same sockets as one that does work?

What they're telling you is that polarity matters in LEDs (but doesn't on a filament bulb). They are suggesting that the + and - are reversed on the socket where it didn't work (and giving you options for how to address that).

I have LEDs in the back of my TV. When installing them, I always test first. One or two always need reversal. The LEDs in my tow vehicle came from my previous vehicle.

The ones I have are 1156's and can't be reversed. I will look at the socket and the two other bulbs I have to see what is happening. I'm guessing the socket is reversed with the housing + and the center contact -, but we will see.

That is a good possibility.

An LED bulb runs a charge through the light, from one point to another and doesn't need a negative wire. A polarized bulb has a + and - pole (socket input), so you have to insert the bulb in a specific direction depending on how your fixture is wired with a positive and neutral wire. A non polarized LED uses a 4 diode bridge rectifier so the bulb can be used in either 12V AC or 12V DC and it doesn't matter which way they are put in.

I have superbrightled's in all of my sockets. They are non-polarized so they go into any 921 socket.

Why they want to send your back, is all you need to do it insert it again and if it doesn't work, flip it over and the positive and negative will be correct.

Christmas LED's

Question that I need an answer..I have an 18'-0 feet length of LED Christmas lights, all are bright white, they are powered by 110AC plug from the house...What would I have to do, if anything to power the string of lights with an 12V DC power source? The reason I asked is this, our deck lites use a timer that converts 110Vac to 12Vdc..the bulbs are filament type bulbs and I want to attach the LED string to this power source by removing the 110V plug? Is that possible?

They would have to be rewired unless you like them dim.

Wiring

Would removing the fuse change them from ac to dc are make them brighter?

No. Connect them to 12vdc and see what happens. You may need to try both polarities.
