Wiring steaming light

[Halo]

I am replacing my combined steaming and deck light with a led one. There are three wires. Yellow,Brown and white. I assume one of them is a common negative. Any one know which one?

Could be any one. Suggest you check at deck socket with multimeter.

The Osculati one is : Yellow wire is the masthead light (steaming Light), the brown wire is the foredeck light, and the white wire is the negative.

Thanks Chaps. It’s the Osculati one

Surprised there was no wiring instruction/diagram if it is a new LED?

Annoyingly, they come with no instructions.

Interesting color choice. EU/IEC 12 V L- is gray. US trailer wiring uses white for 12 L- ground, which is also weird.

Comments please. Are these generally correct?^^ I've seen some variations.

Stuff from China can be any of these, depending on where they think it is going.

I brought to Latvia my old trailer board ..... wired up to use the standard multi pin trailer socket for UK cars. It was a pre-wired shop item - so not my work.

It did not work here with a shop wired socket in Latvia. I was getting daft things like Indicator light come on instead of brake light .. various mixed up and some just not working. Took ages to sort out ...

There was me thinking that this should be pretty well universal ... silly me !

As to wiring ... OK - the OP's question is answered and hopefully solved ....

When I have such - I get a battery and connect wires ... as I identify each - I stick a bit of tape on and write + / - / GND as found on the tape. If the light can be disassembled .. GND wire is usually quite evident.

These colours do not comply with the Iso standard.

This lamp , therefore, has no place on this forum.

Iso does not comply with ISO, therefore the reply has no place on this forum ( with flowers).

I installed one of these.
The decklight is very bright but whenever it is turned on the receive on my VHF is completely blocked by interference. Might be worth checking if you have the same problem.
I don't use cheap and nasty vhf coax and don't have a join anywhere between the mast head and the radios. I have tried ferrite rings with no significant impact on reception.

That is a known matter with some LED's ....

Ferrite rings and twisted pair wiring is only effective for wiring and not the LED itself.

Thanks. I shall check next time I'm on the boat. My VHF is installed with what looks to be a very high spec circa 10mm diameter cable so it will be interesting to see if this makes any difference

The USCG lists nav lights, and to get a listing, they must be tested for VHF interference. A steaming light would be included. This is not part of the ISO standard? Non-USCG list lights are not permitted on US boats (although it happens a lot ... then the VHF does not work).

Good point but tsb240 said it was the deck light that gave the problem. Probably meets the standard but skimped on the second function

Marine LEDs are supposed to include circuitry to eliminate this, which is why cheap non-marine 12volt LEDs are not recommended for marine use even though they would work. I'm surprised an Osculati LED would cause interference, possibly worth getting a replacement if it's new enough?

 

[Never Grumble]

With the Oscaliti does anyone know if this interferences happens when the navigation light part is lit. It is not often that I could envisage having the deck light on when I am using the VHF so could probably live with that causing interference.

I had interference on my VHF from a PWM solar regulator.

I fitted some electrolytic caps across the regulator and the interference stopped.

The bigger the cap the better but must b at least 20 vdc and connected correctly
