Back 20 years ago I received the rear reproduction lights for my 37 and they both had the hold in the top. The do have the drain holes in them so i put a bulb/grommet in the right side, painted the bulb and its been going strong for over 20 years..... and while don't drive it in the rain intentionally I've been caught in the rain many times and so far no problem.
....not telling what reproduction is like today?!
