Purchased the Verdera 20" in 2017, in under 2 years the lights started to flicker and eventually the wire broke due to flexing.  No more lights.  Found the replacement wire part number so no need to replace the entire cabinet.  Kohler should make this part's availability more evident in the parts links.  I ordered extra wires as I expect this can happen again, but here is a work-around that I hope extends the wire's lifespan:  flip the electric cover upside down.  You will still be able to secure it with the same hex screws and screwing them in from the top is far easier.  It allows more wire to be extended out straight which reduces the kinking that causes the wire to break.  Can't do that as well when the wire comes out from the bottom.    You will not miss the extra 1/8" of width on top when upside down.  Also, the mirror is corroding under the glass and creeping up.  For the price paid this should not happen.
