How to remove OEM cargo light lenses? Upgrade bulbs/LEDS?

[traxon]

I was wondering if I can easily modify the small/lower OEM cargo lights? I know toyota sells the upgraded cargo lights, but I just wanted to try and put brighter bulbs or LED panels for the lower lights. Is this possible? I was trying to pop off the lenses to take a look, but I couldn't get them to pop off, even applying a lot of force. Pretty sure they're going to shatter if I pull any harder. What's the trick??
