I didn't care much for the enclosed "spot" style reading lights in the bed area of my truck camper after having frosted glass fixtures in my previous truck camper. The frosted glass fixture was also a reading style lamp, but it gave off light through the glass rater than being a focused spot light, so they helped light up the bedroom area.
I found a similar type reading lamp for my newer truck camper and did the upgrade.
Here's a video of the upgrade projectThe new lights made a big difference in lighting up the bedroom area.
