Burstner T690 rear light removal?

[parso]

Hi does anyone know how to go about removing the rear nearside light cluster on the Burstner T690 please?
I need to access my shower valve and think that that would be the best and easiest way.
The light cluster only has some odd 'caps' on it and no screws visible and the 'caps' don't seem keen to come off. Nor do I know if the whole cluster is stuck on with any kind of sealent either!
any help and or info would be good thanks!
