What exactly are you saying? Are you suggesting that wires carrying 12v
DC
going to the LED lights somehow interfered with the VHF signal in the
coax?
Doesn't seem very likely.

It is very likely. Many of these LED navlights have a switching regulator,
which switches the current on and of with a high frequency to regulate the
current through the LEDs. These switchers can produce a terrible
interference, even on VHF.
