Looking for flat rubber gasket for Winnebago Part #18387-01-701 backup lense

[bcoldpro]

I have replaced the rear tail light lenses on my 2016 Winnebago Mini Winnie 22r including the clear backup light lenses.
The thin rubber gasket for the clear center lense is pretty beat up and not sealing as it should. The Winnebago part # for the clear center backup light lense is #183787-01-701. Winnebago parts does not have a replacement gasket. Gasket is thin flat
rubber that I measure to be 3-7/8" in diameter.

Anyone done the same and managed to find replacement gaskets for the clear center backup lights?

I rarely trust the rubber gaskets for long as the sun seems to degrade them way too soon.
If this is a lens that you find it might work, I recommend just using a good silicone caulk on the edge. With a rubber, I assume there are screws to hold the lens?
This may have some advantages as it allows you to also leave a small hole at the bottom as a way to drain any water that does come in, rather than filling the lens to a point where it can run in or mess with the bulb holder!
I find silicone to be my fav as I used it a lot on aquarium repairs and find the biggest "trick" is getting the surface totally clean of any other caulk/sealer that may have been used before.
Cheap bottle of rubbing alcohol does it for me.

Is it within your realm to buy a sheet of gasket material, trace the outline of the lens onto it, then cut it out?

Push come to shove, that's what I will do. Good idea! Thanks!

My problem with any solid material like we might call rubber, is that it degrades in ways that make it hard for me to spot when it begins to leak. It gets cracks showing almost immediately and how to determine if those cracks go far enough to leak is my big problem. If I use a good caulk, it lasts much longer and rarely develops cracks.
I can look at the caulk and when I do see cracks, I know to redo!
Maybe just a personal thing but I rarely seal with gaskets when outside if given a choice.

use gasket material 1/16" Neoprene and trace & cut it out yourself .. neoprene won't crack and degrade like red rubber does

Hallelujah! I went to the Command Electronics who manufactures the rear tail light assembly on my 2016 Minnie Winnie and found replacement gaskets there! Very inexpensive. Around $15 for purchase (2) and delivery. There's all kinds of good deals on replacement items. "Even the Blind Squirrel sometimes finds the Acorn"!

I decided to replace the large gasket that goes between the rear light assembly and the rear of the turn signal-backup signal housing after the last rain we had. I could see little rain had seeped into the full lense I installed. I contacted Command Electronics and got a next day response to confirm the availability and price. Again, really reasonable at around $7 each gasket. My other order hadn't shipped you so they combined the gaskets I needed into a single shipping thereby saving me money. I spoke to Command Electronics in person and found the ladies there to be super helpful and friendly.

Sounds like a good place to know about!
As a second idea to try to head off potential trouble, it may pay to look at how the wiring comes into these lights?
Just a suggestion without knowing much about the lights. But there are many RV that have wires coming out of the wall and into the lights in a way that any water leaking in will follow the wires to the wall.
Once water gets inside the sealer/gasket, it may wind up following the wires into the wall space before dripping off. That can lead to slowly rotting the wall and that gets into a real problem if allowed to go too far. RV walls are not built to stand much abuse and water delaminates them or rots the thin stuff really bad!
While looking at sealing, try to avoid these sneaky points that do their dirt out of sight and out of mind!
