Identifying postive/negative on LED driving light

Hi guys,
I came into possession of the pictured driving light.
I have no idea of the positive and negative terminal identification to wire it up.
Any help is appreciated.
Thank you.

 

It has two connectors.
That looks like a red/yellow side marker.
Possibly side marker and directional.

Don't recognize those plugs as something we have here in the States.
You could try connecting them with a one or two amp fuse inline.
It'll either light up or blow the fuse.

 

Hi PJMax,
I can't see "red/yellow" marks. Did you mean the white dot in the second picture? That is just a blemish.
I think these plugs/sockets are called "Deutsch plugs/sockets". They are a type of waterproof connectors used in many automotive applications.
The issue I am having here is that apparently there is no standard which one each manufacturer of can use as the positive/negative in these driving lights, whether it is the left side pin or right side one. Or may be there is a standard the manufacturers adhere to, but I am simply unaware of it.

I can use a fuse, but if I get the positive and negative wrong, that would blow up the LED light circuit, would it not?

I'm thinking I can use a diode, but don't have a diode with me right now. Somebody who's familar with these driving lights would know which one is positive by looking at their wiring.

Thanks

 

Thank you for the replies. Actually, they can be incorrectly wired without damaging them. When connected wrong, they simply won't turn on. LED's are diodes apparently and can withstand the reverse of their nominal voltage range without burning them.

 

Looking at the face of the light.... I see a red area and an amber area.
Makes sense as you have two connectors.

No.... LED's cannot be connected in reverse on DC. They will fry instantly.
More than likely a series diode was included inside that light to protect from reverse connection.

 

I have connected many LEDs for less than a second to test polarity without damaging the LEDs. (single LED, LED strips, LED lights similar to yours) Who knows, maybe I'm just lucky?

 

I have dc 12 volt landscape lights on my steps to my house. They have the wedge style bulbs. When I change a bulb I plug the bulb in and if it does not light I remove it and turn it over, put it back in and it lights. They even state in the instructions that is how you do it.

 

Here is a discussion on whether you can blow out a led with reverse polarity if anyone is interested...https://www.wranglerforum.com/thread...ights.1928442/

 

There is a 50-50 split in consensus. However.... connecting a raw LED up backwards in a DC circuit will blow it out/open. If the LED is in a package like a push-in bulb that can be inserted in either direction.... there is a regular LED in series with the LED. The regular diode will block reverse polarity damage and the LED won't light.


An LED can be connected directly to an AC circuit with no regards to polarity.

In the OP's case... there must also be a blocking/protection diode in place.
This is an exception rather then a rule as that diode costs money in production.
On a device with a polarized plug.... reverse polarity is not anticipated.
