Taking the light you set aside, hold a side button down for 1s until the light turns on. The light that was in pairing mode will turn on too, and the lights are now grouped together.

Unpairing Lights Without the App
The unpairing process is essentially the same as the pairing process, but it assumes you start with an already-pair Light (to-be-unpaired), along with one or more Lights that are in the same group:
-
On the Light to-be-unpaired, hold a single button for 5 seconds.
-
Verify that the light is in pairing mode (LED will blink once per second)
-
On any light in the existing group, do an extended single-button press for a Group On/Off command
-
The Light to-be-unpaired is now unpaired from the group!

Greatest product excelente
Great lights. Recommend 2 for best light spread
Best Product Ever, I’m surprised how it works with Bluetooth, water resistance also, Battery is fair enough for night ride.
I purchased the SL-FX and while it's a great light, it malfunctioned within a few days. After contacting customer service they responded within hours and sent me a new one which has worked every since. It's a mark of a good company to stand by their products and their customers this well. Great lights as well.
Support is amazing, lights are great!
I have several ShredLights products and use them regularly for all of my PEV items and gear. These are a very important part for my protection! I’m actually going to buy a few more just because of the Linking Feature!
These work great can’t wait till they add new modes
