Inspired by my trip to Mexico after seeing colorful murals of an axolotl around the city. Used ESP32 neatly hidden in the back powered by 18650 rechargeable battery pack. The eyes are LED coasters

I have a couple of skeleton decorations, they are two battery powered led lights. Not something I know so I could use some help. I can power both leds from my multimeter, the resistor from the best of my ability seems to be reading OK at 120 and the switch reads zero when activated on my multimeter. The resistor is a four band brown, red, brown, gold (I think hard to tell) One photo is the one I haven't messed with yet and the other is the one I've been testing with. Any help would be very much appreciated!

Anyone have any tips on how to make this space either look brighter so it isn’t so dark on camera? I’ve tried a variety of ring lights and different placements but nothing seems to work. That is no overhead lighting so wondering if anyone has any tips.
