Couple of questions,lights and stove hood vent

I just took my lens off last Sunday. 2009 Wildwood by Forest River to replace the bulb with a LED bulb. 2 small plastic tabs on top and 1 on the bottom. Used a small screwdriver to pry down carefully on each of the top 2 tabs and it popped right off. Bulb size was 1156. Of course every other bulb in the trailer was a 921 so I had to order a 1156. I got up on a ladder so I was eyeball to the light and it was easy to see the tabs which were not visible from the ground.
