Yes, it was me.
I was trying to understand how to access those screws.
I have a copy of the fitting instructions (if you can call it that!) of those lights; but I'm afraid they won't tell you very much.
I had to figure it out by myself but eventually got it ... Did you also know that these are lights for a trailer and not a motor vehicle?
If you wish, I can post a copy of same to you to your address and you'll know what I mean.
