I just put mine on a month ago and they are noisey. I can hear them ticking. None have failed yet but I'm keeping a close eye on them.
I also noticed that the new ones I got looked funky in the little clear plastic piece on the outside. Looks like where they used epoxy to hold the electrical parts in it. Its all filled with air bubbles. The just look poorly reman'ed

Is this common and alright to leave alone? I have no idea.

Mine are exactly the same as yours
