Precautions for Light Strip Cutting!
When you need to cut the light strip, you can find that there are many such dotted lines on the light strip. This dotted line is a dividing line because the light strips on both sides of the dotted line have different functions. Take the following picture as an example. The left OU near the dotted line is the output end of the light strip signal, and the right IN near the dotted line is the input end of the light strip signal.

Refer to the picture below. You can see that there is still a remaining part of the OU signal output end within the red frame. In this case, the control signal cannot be transmitted through the IN signal input end, which will cause the light strip to fail to work normally.
