So, today at my parents', my mom had a few projects for me to do for her. One was to change the light bulbs in one of their garage door openers. Both incandescent bulbs were burned out. I replaced them with two brand new LED bulbs, but neither light bulb worked. My mom found a working incandescent bulb and that worked, so evidently, LED bulbs don't work with that opener. Very strange. She'll now have to get some regular incandescent bulbs for it work.
