12v Lights from set 7867

[alan_muhl]

Some time ago I acquired some old lights from set 7867. Now I want to make them function on my Lego town/train layout. First question is how do I connect them? Meaning, what do they plug into (transformer, etc)? Next is how do I power them in the US?

I have looked for documentation on these subjects but can't find any good source that simplifies this for a guy who doesn't have an EE degree. So I am looking to the Lego train community for some help and guidance.

Hi Alan, you'll need to get yourself a 12V power supply/transformer like this one available via Bricklink: http://www.bricklink.com/search.asp?itemID=5563

You can also find them on eBay. I'm not sure if they were ever sold in the US for you to get one on the correct voltage. If not you'll need to get something that will step down Euro voltages to US voltages. I'm just lucky that Australia uses the same voltage as Europe!

The lights are usually connected via the connector holes on the left of the transformer like in this example in the set instructions:

I hope that helps.

Thankyou very much. I already have the transformer, just didn't know where to plug the connectors in. I also may have a device to step down the voltage. Cheers.

I think since the US is 110V and most of Europe is 220V you'll want a step up transformer. It might be far easier and more energy efficient to use a normal 12V train power supply designed for your local sockets.
