This kit has no Lumen output mentioned but does have this in the description:
2. Design: Multifunctional split design, the main light and left and right turn signal can be used in splicing, or can be disassembled and installed independently, free and convenient, and escort your night riding.
As you can see from the description they're only good at night. Which is why they're probably so cheap.
Here's what I use:
