20x LED BATTERY-OPERATED LIGHTS
20xLED Battery Operated Lights, retail $7.99
Manufactured by (Unknown) for Right Aid
Last updated 12-06-20
I found this light set at Right Aid for 50% off, and being the LED nerd that I am, I *HAD* to have them.
The light sets contain 20 warm white "blob-type" LEDs.
They can only be set to all operate continuously.
Lighted length is advertised as 12.10 feet (3.68M).
SIZE
Feed the lights first (see directly below), and then you can go decorate that porch.
String these up as you would oridinary (corded) seasonal lights, but handle them somewhat gingerly because the wires are quite a bit thinner than the wires are on corded sets. Hang them on porches, mantles, doorways, or other places where you might normally hang light sets -- or just hang the suckers off your dorm room ceiling for that special holiday feel all year 'round. 
To turn them on, slide the black slide switch on the upper right front of the battery box to the right.
To neutralise them when you are finished using them, slide the black slide switch on the upper right front of the battery box to the left.
The light set has a 6-hours on / 18-hours off automatic timer; simply meaning that you can just "set it and forget it" to borrow a phrase from one of Ron Popiel's infomercials that ran near the turn of the century.
To change the batteries, slide the battery door off and set it aside.
If necessary, remove and dispose of or recycle the 3 used AA cells from the compartment.
Insert three new AA cells in the compartment, orienting each cell so its flat-end (-) negative faces a spring for it in each chamber.
Slide the battery door back on, and be done with it.
Current usage measures 38.30mA on my DMM's 200mA scale.
These light sets appear at least *reasonably* durable, in that they should not just fall apart on their own or through just casual handling.
This product is meant to be used as a Christmas light string in a reasonably dry area indoors (or outdoors because the light string itself is waterproof but the battery box is not), not as a flashlight meant to be carried around, thrashed, used, and abused; so I won't try to drown them in my toilet, bash them against the concrete floor of a patio or a steel rod, let my landlady's dalmations go poddy on them, run over them with a 450lb Quickie Pulse 6 (motorised wheelchair), or perform other indecencies that a regular flashlight might have to go through.
Photograph of the set, illuminated of course.
One suggested decorting idea is to simply cram the lights into a jar -- since I do not have a jar I suffed the lights into a large (~16 oz.) drinking glass.
