Upper rear red marker light

Hi, tried searching for previous topics but couldn't find it.  Anyway,  one of the upper rear corner red led marker lights isn't working on my Autosleeper broadway fb.  Does anyone know how to change them and where to source a replacement please? I'm assuming that they just screw off but not sure what type of replacement bulbs.

Always best to show a photo as so many different ones over the years but AS list a couple in their spares catalogue shown below...

Very hard to see the light in question in your photo. However, if you give A/S your build number they will quote you for a replacement. I've just bought two new ones for my van at £5.70 each plus £4.50 postage plus VAT. 
I can see two screws in your photo. Mine is also 2 screws. Remove those and the whole light comes off the body. The bulb holder can then be separated to replace the 5w capless bulb. Replacement is the inverse of removal.

I have a 2018 Broadway and the whole rear end is led lighting. I think 2018 was when AS changed over to led. I  had to trace a fault in the front marker light wiring and when I removed the light I found that there were two short trailing leads coming from the light. These then joined onto the vehicle wiring with connectors.

Whoops - the OP said it was an LED light but I didn't notice. Sorry

 Thanks.
