Need help on LED strip blinking sequentially

Hello all,

Basically I need a 5 meter long LED strip to blink sequentially (one light at a time and then repeat) except I cant find any online that are 5 meters long, I found some that are about 3 feet long etc that blink sequentially. So my question is can I take one of the 3 ft long ones that blink sequentially and somehow connect the 5meter long one to the control board within the 3 ft long one so the 5m one blinks sequentially? or is there a place I can just buy it… thanks guys.

I can find 5 metre addressable LED strips on Ebay.

I cant find any online that are 5 meters long

Did you look? First google hit:- Ebay
