Quoted from Medic:So I have been having LOUD squealing sound from the lighted side rails for a while. I tried one technique with the hot glue over the coil in the little black box but that didn’t really help. So I noticed that the rails were touching the ground wires on both sides and it would squeal loud when they were touching. So I put electrical tape between them and the squeal is down 90%. So this helped me get rid of the frustration that I was having. I still hear a slight squeal and I’m wondering if I should be using a different tape other than electrical to prevent further interference?
Edit*. I spoke too soon. As soon as the lock bar was placed the noise came back and now I’m getting a little shock. So plan didn’t work

Mine lasted maybe 100hrs then were so dim you couldn't see.
I'll never buy those again
