This is a reflector triangle that has lights.
The lights blink.
This traffic safety triangle collapses for storage.
To set it up, you raise two sides of the triangle, then snap them together.
You then turn the metal base.
There are also two shiny "feet" that add support.
There is a battery compartment, for two AAA batteries, to provide power for the blinking lights.
There are 3 lights on each side of the triangle (9 total).
This traffic warning light stands 15 1/2" when erected.
Each side of the triangle is 18" long.
The metal base is 12" long.
The triangle is made of plastic.
It is in excellent condition.
I only have one.
Note: This triangle will be unstable on a windy day.
