Light Bar - pre-install test?
I've been trying to make one of these https://www.printables.com/model/44341-led-light-bar-prusa-mini and, thanks to my general cackhandedness, it's taken me 3 attempts to get to the point where the thing is assembled, but not wired up to my printer. (During this escapade, I even managed to melt one of my printed parts while heating up the heat shrink stuff around the wires, sooo yeah... that's how it's been going...)
My soldering isn't the best, and there was a fair amount of pushing and persuading to get the wires into place... Before I go rummaging in the electrics box of my Mini, is there any kind of battery powered arrangement I could hook up to the light just to check it will work ok?
RE: Light Bar - pre-install test?
If it's a 24 volt LED strip, two common 9 volt batteries in series (18v) should have enough to light it for a go/no-go test.

Thank you, jsw!! It works! Now, for the scary bit... wiring it into my printer!

Yes, finding the appropriate tap-off point shall be left as an exercise for the student. 😉
How are you at reading schematics and following them on a real-world device?
How are you at soldering?
RE: Light Bar - pre-install test?
Well... my Mini now has a working light bar attached! Definitely leveled my soldering game up during this little project.
