Default Tail Light Lens Drain Wick?

I bought these for my 73 and can’t find where they go.
I’ve looked in the AIM and the Parts and Accessories Catalog and there is no mention of them and they aren’t on any illustrations.
Does anyone have a clue???
Thanks in advance.
Greg

Do they just set in this slot at the bottom of the lens?
it looks like it could be a drain of any moisture build up inside the lens.

Hello,
Yes.
A means to wick moisture out of the lenses.
A filter from a cigarette usually works.
Regards,

Thanks Alan.
Now that I see them installed it makes perfect sense.

@Alan 71
Alan,
Maybe you can answer this. I converted my 1971 backup lights to brake lights and found that my original 1971 backup light housings are date coded to 1968. '68's didn't use this design and in '68 is when the Feds mandated backup lights. In '68 the backup lights were below the rear bumpers in their own housing. Why would they stamp the later design part with 1968 instead of 1969?

This is one of my original 1971 backup light housing:



I knew you'd know about those wicks. Guess I'll have to get some since I just was messing with my tail lights and now know they are missing. Got to love this hobby. Learn something new everyday,

When I restored my tailights those wicks were hard as a rock. I figured on sticking new one's in there, but forgot about them. Glad you brought this up OCB!

Reminds me of another moisture hack at least on my car. There's a plastic membrane under the vinyl panel which covers all of the open area of each door. I don't have a source for it, happened upon it accidentally.

That membrane is a moisture barrier. You can purchase the door panels with or without it from Al Knoch Interiors.

They're called vapor barriers. All 63-82 Corvettes, and most other cars came with them behind the door panels. I don't know, but they may still. Corvette America makes them, and all the vendors carry them.

Hello,

Originally the vapor shield was held in place with 3M black stripping.
I think it was rarely put back in place if the door card was removed.
For a number of years the usual venders sold a flat piece of plastic as a replacement....it didn't work well.

Regards....

Hello ta,

The GUIDE housings and lenses usually have those lettering and numbers but I'm not sure if they refer to a date or???
