I found them again.

AliExpress. I’m pretty sure this is where I got them. Just a few notes on them. they are battery only 3 AAA. No timer. The worst thing is that they ship in random colors. When I ordered last time, I got 5, 4 were flashing Red/Green/Blue and one was solid blue. I’d have liked to have the option of picking colors. Not a big fan of the RGB alternating. Since bulbs aren’t on at all times, it is not quite as bright. Don’t count on using the acrylic it comes with. It is 2 layers of some sort of polycarbonate that doesn’t engrave really well. I don’t know what I’ll use it for. Here’s a link to a topic where I used it. It’s post 14 in the thread. I didn’t know how to get directly to that post - If I quoted just that post, the photos didn’t seem to show up.
They are supposedly on sale for another 15 hours (might almost always be on sale?). $7.32 each including shipping. It looks like they are about $10 if not on “sale”. I guess they weren’t that cheap when I got them, unless I snagged them before a pretty big price increase.
