BTF LED lighting strip help
Hi Everyone,
Please excuse my lack of knowledge on the topic.
I purchased this BTF-LIGHTING 16.4FT RGB kit from Amazon. I then purchased some splitters because I needed the lights to go in two different directions from the power source. The kit came with 4PIN Clip connector and a wire cable that I used to have the longer section of the LED go in and out of a hole (because it required bending).
I cannot get the strip to light. I ordered new parts, thinking that it might be the clip connector or the cable, but it just doesn't work.
I've tried flipping the strip around and connecting it in different ways; I've tried using a different part of the strip that was leftover on the spool.
Still, nothing. I am not an electrician, and I know nothing about doing this. But it shouldn't be this complicated, right?
Thanks in advance to anyone who decides to chime in.
