Lionel caboose lighting

Hi guys I have a Lionel 19471 Prr n5c caboose. It has holes in the side s of it for markers. I do have the stock one however. I was looking to put LED ones in. Has anyone tried this. I found a site that sells them. [url]Www.royztrains.com[/url]. But I am unsure if the side markers he sells with a lighting kit will work with the stock holes from Lionel. I uploaded a picture of one that I found to clarify what holes I'm referring to
