Moisture in rear indicator lights

Both my rear indicator lights on my 2018 Autosleeper Broadway FB (previous individual lights model) have moisture inside. Are they easily removed and dried or will it need to go into a service centre? I presume you should be able to get access in order to change the bulbs.

Remove and dry chech the seal's are are good

How do you remove them? Do they simply unscrew from the outside, or do you need access from the inside? I've not tried for fear of damaging the seal etc.

For warranty purposes surely it would better to take them back as they are? That way the dealer can see there is an undeniable issue.

Dry them out and complain later and would almost guarantee they say there is nothing wrong.

Good point

At the bottom of the light their are ,2 raised Pimple's  push in a small flat screwdriver to the back of the lamp and  prize  upwards and the cover pops out  . if you look up from the bottom their is what looks like a clip .found on other forums  .not personal experience .

We had the same problem on our 2016 Broadway. Fixed under warranty by AS @ Willersey when it was in for Hab check.

To see the clip fixing you may find it easier to use a mirror held underneath the lamp, it is a discreet fixing !
