Bought another set (thinking something was wrong with 1st one), watched the video, checked the polarity, still no luck!!

Polarity should not be an issue. You can come out of the power supply only one way with the main wire, then into this "jumper" and out. Noting colors (e.g. red to red, ensure they match. If not cut and splicing will be required. Excellent product.

These connectors work perfectly with the 8mm LED strips. Most importantly, make sure the + side of the LED strip is positioned beneath the metal clip on the RED wire. The LED strip is marked +/- so make sure the strip is aligned correctly inside the clips. If you're light strip doesn't light up when you slide the ends under the two metal clips, you may have to pull the strip out of the clips just a tad. Just work it in and out until you hit the sweet spot on the LED strip.

It's the polarity which is reversed and don't ask me to explain that. I finally gave up and started using batteries. It works fine and the batteries last a pretty long time. Good luck.

ask the seller. maybe they'll replace the duds. Weird, I've never had even one as far as I know.

i have a 2012 tundra that i installed theses lights on. i know on my truck i had to swap polarity when plugging them in. that means - to + and + to -. that worked for me.thanks, jason

No, no polarity detector. You have to change the connection to measure charge or discharge currents.

Amazon replaced mine and I got the right angle connect plug. Sounds like its hit or miss with amazon and angled plug... and they currently are not available directly as these are under review. Requested a replacement on dec. 24th and got the new set dec. 27th..hope this helps....Joe

I remember having the same issue when I purchased this set. I ended up finding a video on Youtube for instructions. Just type in the product name in the search field. Hope it helps.

I couldn't tell you what is wrong. Both of mine worked fine. Did you try taking one out and trying the other by itself by changing between channels. Did you check the batteries in it, change them just to see. Also reading through the feedback of others says that some people received a set where 1 worked and the other did not. If this is the case, I would contact the seller and tell them the problem. Nobody likes bad comments and you might get lucky and get a new one. Hope this helps.

With a standard 12v DC adapter. Look on the PCB and you will see a + and - sign indicating the polarity.

I don't think so. It's all digital and if you reverse the polarities it won't turn on. They have A LOT of accessories for so they might have a kit that will work. You should contact them directly.

Amazon carries for under sdollars make sure that you get the correct polarity--- Positive center negative outside!!!!

I had the same problem (question). The label on the hour meter says that the connections are polarity sensitive but when using to monitor AC usage, there is no polarity. I communicated with the vendors customer rep., and was told that they had engineered the counter to be able to be used in a AC or DC application, but to save money with parts that had already been labeled, they continued to ship the new design with the old labels. They told me to use the meter (counter) without regard to the plus and minus lables. I tried it and it works.

Start with calling the manufacture and see if they can send you a new battery and a new adaptor. If neither of those work, then exchange it for a new set.

No issue with them yet. If there were, I think I would replace it with one rated for the next higher voltage. This use to happen with some TV's I use to repair, that was the fix. Good luck.

Get the voltage and polarity right and you should be ok. Just be careful not to fry it.

Battery probably bad. If you let NiMH get absolutely flat (discharged) they CAN reverse polarity.

I used AA battery in each of the three that I bought. All worked. Check the polarity. Positive in first. If that is correct, then I think you got a bad one.
