Wiring a light and a battery pack, basic questions

[dragunonov]

Hello
Complete lack of electrical knowledge here. I sew actually, making a costume right now that I need a little light for. So my question is this:
Is the sequance of "battery pack -> negative wire coming out of the battery pack -> wire nut -> negative wire coming out of the light -> light -> positive wire coming out of the light -> wire nut -> positive wire coming out of the battery pack -> battery pack" correct?
This, so to speak:

And would it be possible to insert more lights into this chain?
Perhaps like this:

Any and all insights are welcome and apreciated!!

Seems correct to me. May be worth posting a photo to be on the safe side.

And welcome to the forum!

Thank you!! I'll get some photos when I get back home (at work rn). Glad to have joined, might just take more of an interest to wiring, awaken the kid in me who used to disassemble calculators for fun

I'm back with pictures!!
Sadly, something isn't working and the lights are not lighting up. I'm not sure if it's a voltage issue (im using two rechargeable AA batteries, 1.2V each, in a baterry pack, the lights were marketed as 3V-6V) or if I'm twisting the wires wrong. Thanks to anyone willing to share wisdom

The LEDs appear wired incorrectly back to back - whereas you should wire the black from the first LED to the red of the second LED, etc. So they are all in series.

Agree with SJD. Also the 2.4V you have from the 2 cells may not be enough, but worth a try.
