In the event anyone is looking for an LED replacement or upgrade for their license plate light on their first gen Hannigan GL1800 trike, I have the solution. Ruth Anne at Hannigan sold me the LED replacement a a reasonable cost. You can either call her or purchase yourself at Online LED Store. It is actually listed as a courtesy light: https://www.online-led-store.com/2pc...zledsil0122-ch

You can purchase a 2-pack or a single.
