As far as bulb polarity, which part of the bulb is positive and which part is negative? (i.e. Connect bulb tip to positive or negative?)

I don't think it matters since this bulb can operate on AC or DC. But I believe tip is positive.

The plan is positive the shell is negative it will work either way but you don't want the shell positive or is easier to ha e a short

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.

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

As Matt & Robert already stated, the White is negative (ground -)Black is positive + (low bearm) and Red is positive + (high beam). Tie the red & black together for single brightness (high) backup light.

Sorry, Allthumbs16; I gave this as a gift and didn't try it out. However, I was told by the person I gave it to that you hook it up between positive and negative.

by the look of the drawing on the side, 4 goes to the positive on the coil on the SSR and 3 goes to the negative to the coil of the SSR. but I would be surprised if it polarity matters on the Solid State Relay.

Polarity is embossed on the ceramic substrate with traditional symbols of positive and negative. If you can't locate, use s multi meter as it is a diode and only passes current from negative to positive

The red wire connects to the center pin, the black wire to the outer ring. As far as polarity, it depends on what being plugged into it. If you want a pos. center pin connect the pos power lead to red. For a neg. center pin, connect the neg. power lead to the red wire.

It is those thin pieces of metal sticking out to each side. I slide the wire through those little holes then apply the solder. The + & - are a bit confusing. What I have found is ....if the LED is laying flat with the + in the right hand corner near you, then the + terminal is on the side opposite you. If you hook it up backwards.....it just won't work, but no damage.Make sure it is heat sinked with thermal grease......otherwise it will burn itself out in just a couple seconds.

Strange why it would even be masked at all. Also, I can't quite make out the tip polarity. Anyone know?

That would be my guess. In my flashlight the positive side of the battery goes in first, and has the knob that would touch the inside spring. But that's just a guess. I've not used the bulb for any other applications.

I haven't had to change one yet, but I believe the whole lower assembly (silver ring and glass) twists into place on a mounting bracket. I assume you twist it slightly one way or the other and it will drop from the bracket and reveal the bulb. Hang on to it, seems I remember it being heavier than you might expect.

Yes polarity matters. I don't know which is + or - however. I tested it one way, didn't work, reversed the polarity, worked.

send it back for a refund. You need both prongs in order for the bulb to work. :) Hope this helps.

Yes but when u replace halogen bulb prongs on LED are set to match polarity correctlyd

The pins shown are called a 'G9' configuration, lots of companies make them and they are a stand bulb type/size. They come in several wattages also. The pins shown on either side are the same, the bottom of the bulb is flat and the bulb can go in either of 2 ways, no polarity requirements.

Hi Pat,The 4 prong connection sounds correct. Your old bulb assy. will have the model and type printed on it. I recommend you replace it with the same.
