I have one on my 2023 Plus Four. It has the Cobra light but that gets obscured by a suitcase. I bought an LED light and cut the supply to the Cobra one that came from the spare wheel well. I used Waterproof connectors to do a quick swop of the lights. Superseal connectors. There are you tube videos on how to use/fit them.
I strap the light to the suitcase with a basic strap, the LED light is fitted to a strip of oiled wood that slides onto the strap. Quick and easy to do the swop when needed. Only one light works with this set up so it's a Cobra or extra, not both.
Note, for the Plus Four there is a plastic cover below the spare. I removed this to get at the original connector plug , cut that and extended the wire as I needed the new connectors outside it. Then fitted the Superseal connectors. This kept everything watertight. Well up to Morgan standards anyway!
