Are these polarity conscious? If so which should be pos/neg?

These aren't polarity conscious. It doesn't matter which way you install them.

You could technically make either positive or negative. Just dont mix them up. If youre asking a question like this you might want to have your home theater system professionally installed. Personally I use the white line as the power positive red....black is clear ground.Good luck

I have seen small variances, but it doesn't have anything to do with the concentration because I tested them on someone who had smoked of course it was + , one who had not smoked in 30 days- neg, and someone who has never smoked also neg but the line was pretty much the same shade. Also, we did get a negative reading and probation got a pos one time and that was well after anything had been ingested.

these have 2 wires that are color coded, I don't remember what the colors are, but just hook all of the same color together and apply positive to one and negative to the other, if you have the polarity reversed they wont light. These are mega bright, 75 together is going to be a hum dinger of a light!

Sounds like a loose wire. I did have another brand of led side marker light that did that. After I tried everything I reversed polarity and it worked. Just a though if you haven't found the cause.

Yes.....but be CAREFUL that you keep the polarity correct....(+ to +) (- to -) if you want to know how to know which is witch ......The plug with the shinny end..(the tip) the shinny part, the outside is (-) the inside is (+) .....I hope this helps...don't be afraid to ask....JIM

Make sure the polarity is correct. Also make sure there can be no motion for it to detect. These are sensitive units. Good luck!

Left side. Ist battery put pos end in first, repeat with 2nd battery on top of 1st, On other side do the opposite. Put neg end in first, repeat with 4th battery, Battery configuration form a "U" shape . With cap off you should see neg end on left and positive end on right With batteries on same configuration on each side. Make sure you align batteries with metal part in cap when screwing on. Wish I could draw a diagram

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

At the back of the unit you'll see the letters "L" and "N". Follow the line, "L" is (+)pos and "N" is (-)neg. Hope this helps.

I was emailed by amazon and asked to reply to your question. Bottom line is the ones I got are only two wire (brown and green ) and polarity does not matter with them. You are safe testing by randomly touching the wires to the battery leads to find out what will work.

As far as I know the bulbs are not polar sensitive. After wasting a lot of money on other l.e.d.'s , I found these to be the best and brightest so far.

Polarity has nothing to do with venue size. Speakers have drivers, which vibrate forward and backward very quickly to make sound. If you have two speakers totally in phase, they will vibrate forward and backward at the same time. If they are totally out of phase, one goes forward while one goes back. This will make the sound quieter than if you had just one speaker. You want your subs, mains, and any other speakers you have to be in phase, if they are not then you can reverse the phase on the subs, which will cause them to move back when they were moving forward and forward when they were moving back, and hopefully that will realign the phase of all of the speakers.

There is NO polarity switch. If using a projector, you'll need to use the invert on/off to resolve issue (not a big deal)

The product picture shows polarized prongs, if you magnify it (hover mouse over the picture) you can see. Assuming this is an accurate picture, looks like the answer to your question is "Yes."

The post on the right is red, so it would be positive. The post on the left would be negative.

If you are asking if it shows you that the Hot line and Neutral line are right, reversed or flipped for an AC voltage, then yes. The word "Polarity" is usually referring to a DC supply voltage. This is an AC 120 volt receptacle tester only. The GFCI button, on the tester, is for a Ground Fault receptacle only, and should not to be press while plugged into an standard receptacle. There are three lights that indicate the status of the receptacle. One red and two yellow. There are six status indicated conditions that are on the tester. They are OPEN GROUND, OPEN NEUTRAL, OPEN HOT, HOT/GRD REV, HOT/NEU REV and CORRECT.
