How to insert batteries into Lighthouse L81 UV Lamp

I recently acquired a Lighthouse L81 switchable UV lamp so that I can check my stamps for tagging. It’s a neat little portable device that can be used to check for fluorescent or phosphorescent tagging, and it’s priced at a fraction of what larger models cost.

One of my first questions, though, was, “How do I put batteries in this thing?” It’s easy enough to remove the battery compartment door, but the battery orientation indicators molded into the plastic on the inside of the battery compartment are difficult to see if you don’t have the lamp tilted at just the right angle.

I did eventually figure it out, and thought I’d post a “how-to” video in case you have the same trouble I did.
