Ordering Relay or replacement

I have a question about the Signal light. We are missing our Relay for it and I am wondering where you can order a new Relay for the Signal Light or if there is an appropriate replacement Relay we can use?

The part number for the relay is 700-SKOC2Z25, it is a Rockwell part so you can get it from any Rockwell dealer. If you did not receive this part in KOP then you should contact First Parts through the website.
