4 PCS USB LED Car Interior Atmosphere Lamp, Plug-in Mini USB LED Light for Auto Interior Decor, Portable Ambient Lighting Kit Universal for Most Vehicles, Car Accessories (Red)

I ordered these USB LED atmosphere lamps to put in the back seat of my pickup truck so my kids would have some lighting as we drive at night. This is the “slow flash” variety, which means that each of the three LEDs will rotate colors randomly every 10-15 seconds.When first plugged in, the lights give a nice Red, Green, then Blue color. But over time, the randomness leads to a predictable outcome. That is, the eventual output of these lights is a consistent light-blue color. The advertisement says “variety of colors to choose from” which is false. I have found no way to choose a particular color and remain with it.Regarding brightness and power consumption, I’ve found that these are OUTSTANDING emergency lights. I plugged one into a fully-charged 18650 (2000 mAh) battery bank, and it ran for over 15 hours non-stop before I eventually unplugged it. These days it seems that everybody has a few power banks laying around. Just plug one of these lights into the battery and you’ve got an all-night candle without the risk of spilling wax, or causing a fire.

I recently ordered these lights for my jeep’s interior for the back seat area. The colorful slow flash mode creates a relaxing and vibrant atmosphere during night drives. The lights are easy to install—just plug them into any USB port and they instantly start working.I do like that they are compact in size, which means they don’t take up much space and aren’t sticking out too far.They are more of an ambient accent rather than a primary light source. Despite this, the overall effect is great, and they are a nice way to personalize your car’s interior.

You get 4 lights in the bag. They plug directly into any USB power bank or outlet and they light up nice and bright. They go through a set pattern of light colors. In a car, they would be pretty cool. Though a bit distracting.I plugged them in around the house. Wherever I had a spare connection, in they went. When you want to turn them off you just unplug them. Easy.

This item is skimming across the mark it has sooo much potential if it had a brightness setting
