The bulbs are the 10 watt pin based halogens used in many interior fixtures in my vintage coach. The bottom fixture is easily removed from under the sink with the drawer out. The top fixture looks much more difficult to me. It almost looks like the fixture is slightly larger than the access revealed when the tube has been removed. I have changed the bulb in the upper one by grasping one of the pins with long nosed pliars to insert the bulb. I finish up by pushing it in the rest of the way with a vinyl glove covered hand to prevent contact with my skin and the bulb glass. To get an led in there might require removing the reflector, but I am not sure on that. Russ
