This is a vintage 4-light marker relay unit. It has been stored in a warehouse for a long time. I haven't connected it to electrical components, so I don't know if it works properly. I tested the relay unit itself by connecting it to a battery, and the lights displayed are relaying, so I've confirmed it's working. 24v specification. Everything in the photos is included. It is being sold as junk, so I do not accept any claims or returns. Please refrain from purchasing if you are sensitive to such matters. Search terms: Dekotora, marker lights, relay unit, 4-light
