Rear brake light LENS removal DIY?

[Riko_imp]

I am thinking of replacing the rear brake light with this LED version from Endurance:

I like the LED look of it, but I don't like the smoked or the clear lens they provide with the kit...so I want to keep the stock red lens.

So today I decided to take a look at the rear light module and saw that you could remove the lens, but I wasn't too keen on forcing too much that would brake the tabs holding the lens in place.
2 tabs at the bottom, 2 tabs at the top.




Is there a technique to unclick that lens from the module?


Thx
