American Greenpower 12 Volt LED Set

This four-piece set contains dimmable USB LED bulbs shaped as S14 glass bottles with visible Edison-style filaments. They operate at 12 volts and produce a white light appearance suitable for cars, bedrooms, hallways, nurseries and camping. The touch-control interface allows simple tap and long-press operation.

Touch Dimming From 10 To 100 Percent

Brightness adjusts continuously from 10 percent to 100 percent by long-pressing the glass surface. A single tap turns the bulb on or off without mechanical switches. The flicker-free output remains stable throughout the dimming range for consistent ambient or task lighting.

USB Power Limits Fixed Installations

Each bulb draws power from a USB port so it cannot replace mains-voltage fixtures or standard 12 V automotive sockets without an adapter. Buyers who need direct wiring, higher lumen output or weatherproof housings should look elsewhere. The 1-year warranty covers the supplied units only.

Questions about this item

How much heat or power does the 12 Volt LED bulb draw when left on all day?

Each 12 Volt LED filament runs cool and draws minimal current, so continuous operation adds negligible heat or load to a USB port or car socket.

What power source must I already have for the USB touch-control bulbs to work?

You need any standard USB-A port — laptop, power bank, car charger or wall adapter — that supplies 5 V power to the plug-in base.

Will the S14 Edison-style bulbs fit the vintage sockets I already own?

The S14 base matches classic S14 sockets, so the bulbs screw directly into existing fixtures without adapters.
