If you cut it at will, it will cause the unit not to light up. For example, if it needs a length of 8.5 meters, the light strip should be cut 9 meters.

2, link plug, LED itself is a diode, DC drive, so it has positive and negative poles. If the positive and negative poles are reversed, they are in an insulated state and the light bar is not bright. If the connecting plug is not energized, just remove the other end of the light strip.
