Lighting above sink

Has anyone replaced square lights above the sink located in wood decoration
We have a 370GB lights are starting to fade above the sink area
Cannot seem to locate where to purchase

I haven’t had any of those square LED lights go bad yet. If they’re similar to other LED lights I’ve come across, you might be able to just pry them down a bit to reveal a couple of spring loaded clips. They should have some identifying markings that could help in getting a replacement.

I did that with the other style LED lights Vanleigh used and found some close replacements by searching on the part number I found on them.

Assuming you’re talking about the ones circled in the photo below.
