I'm trying to make a lamp from my gf's favorite beer. It's a bomber(16oz) bottle that I'm running a DIY lamp kit through. I'd like to add two little red LED lights that are connected to the switch of the lamp so that the lights act as little red eyes on the bottle. Does anyone know if this is feasible? Will it need its own power source or can I run some extra wire from the light switch and power those two lights too? I have zero experience with this and could ultimately do the project without the LED lights but it would be that extra special touch for the holidays. Any help or pointing in the right direction would be greatly appreciated.

The easiest way to run an LED off of 120VAC is to use an LED that's already designed for 120VAC, like a 120VAC LED Panel light. They come in a wide variety of sizes, colors, and form factors.

Just keep in mind that 120VAC is dangerous, and if you're not actually going to panel mount them where only the front of the LED is exposed to the user with the rest of the LED shielded by an insulating or grounded panel, make sure that you keep them safely isolated so the user can't inadvertently come into contact with the back side of the LED housing or wires.
