Title: GM 4108 Corner Marker Light Lens
Post by: richard5933 on June 12, 2019, 06:18:14 AM
Both of my front corner marker amber lenses are cracking and need to be replaced. Hoping to find some new ones. Mine have "Cats-Eye No. 87" on them.

I know that GM used the same or similar lights on a few different models, like some RTS buses and the 4106, but not all of them use interchangeable lenses.

Anyone know which other models use the same front corner marker lenses as the Buffalo buses? Knowing this will help my search chances.

Thanks.

Someone on BGM showed me that. He sent a note to the seller on my behalf - still no response.

I don't have FB, don't want FB, and even if I did network restrictions keep me from accessing it.

Would be nice to know what the full story is on these - I found a listing on eBay and contacted the guy. He's got Cats-Eye 87-L and 87-R aluminum housings listed, but they look like they are two different sizes which doesn't make sense.

He's always my first call. He only has the red/rear lenses, not the amber ones for the front.

They were used on so many models I'm hoping that there's a set out there. Just gotta find it.

Their phone number doesn't work. In the past I've tried calling them about other parts - they said they'd check but never got back to me. I'm guessing that they are having problems for some reason.

I had similar trouble with them a couple years ago. I requested prices on a bunch of stuff they had listed, but they never got back to me. Maybe they are out of it now.  ???

Until I find replacement lenses, I'm wondering if anyone has tried doing things to reinforce old lenses?

What I'm thinking is using some type of clear & thin epoxy to coat the inside of the lens, hoping to seal any of the many fine cracks developing and to keep things from getting worse.

Thoughts?

When I had my 1957 MCI Courier 96, the front turn signal lenses were brittle and cracked from age and sand and gravel bombardment. I remember applying a 3M clear film over them. It worked well. You could not tell from a few feet away. Not ideal, but I never found replacement lenses.

I wonder if the vintage auto peeps have a suitable product or procedure?

They are more stuck than we are for unobtanium plastic.

Only the most popular models get reproduction parts. The rest must be doing something successfully?

Happy coaching!

For me there are two reasons...

I have no desire to be on FB, and our network security rules prohibit it even if I did. I could get an external device to use FB, but like I said I don't want any part of it.

There are multiple ways to reduce tracking by the big tech sites. Browsers have incognito mode that eliminates tracking cookies. Use another search engine than Google search. Do not log into Google account to reduce tracking. Numerous other strategies if you care.


Use Google to search how to not be tracked. lol

Not sure how all this has anything to do with the thread or my finding the lenses for the marker lights.

I'm not really interested in getting into a lengthy conversation about the merits of FB, our network configuration, or of why I am or am not using FB.

I understand that not everyone will agree with the decision, but how about we get back to the topic at hand here, our buses and how to keep them running down the road as well as possible.

The lead I got from the guy on BGM about the lenses on FB didn't pan out. Seems like the guy wants to keep the lenses for his bus.

There is a possibility that I've found two sets of lenses, but they are both for the same side of the bus. At least it's a start. If that works out I'm halfway there, and I might even have a duplicate to sell if anyone else needs. I'll know for sure later today hopefully if I've got them locked in.

If the ones I am trying to nail down work out, I'll be covered for the front-left and the rear-right.

I'll still need the front-right and left-rear.

Figured I might as well get a whole set - if two are failing the other two are not going to be far behind, and once moisture starts getting in there troubles will surely follow.

Front right get eaten by tree branches, those are the tougher ones to locate.

Facebook is unmoderated and there's a lot of really stupid info on there amongst interesting bits.

Is that one an 'extra' on a parts bus? If so, hold that thought for just a bit until I see what comes up in the coming weeks of searching.

Yes is on the parts coach. My conversion was  Eagle capped by former owner and uses off the shelf clearance lamps.

I've exhausted my leads for now. I've secured NOS replacements for all but the amber front right corner. Initially I thought that I only had one lens with problems, but as I made my way around I realized that all four were going bad and letting moisture in.

So, I'm going to take you up on this so that I have something up there which has a hope of keeping things dry. I'll send a PM with my contact information.

Amazing how a lens can look so good but have so much damage behind the scenes. Glad I noticed all this before one just fell apart down the road.

Thanks. Since the front right is the last one I need that would be great. While you're pulling stuff, is the bezel on the front left still in good shape? A previous owner buggered mine up drilling holes in it to mount a temp sensor and a replacement would be a nice upgrade.

I'm waiting for some dry weather to  attempt removal. May have to use a carbide burr to remove heads. Have done it before, it just takes some time.

Okay - makes sense. If your spring has been like ours I fully understand. Very wet and not particularly warm.

Guess I have been lucky, as so far I've been able to remove all of the lights using a #3 Phillips on the outer screws, sometimes with a wrench on the shaft of the screwdriver. The inner plates are easier.

Richard,Wonder if these could be duplicated on a 3D printer??

I've seen other lenses which were recreated with 3D printing, but to me the results were quite disappointing. The result is more opaque than translucent, and the finish would require quite a bit of polishing to look like an original.

I was going to post on this thread today actually, as I've been able to obtain some lenses for three of the four corners. The ones I found on eBay worked out. I do now have one extra right-rear and one extra front-left.

The front-right amber lens is the only one I'm still looking for. It's not the one I started out thinking I needed, but once I pulled them all it's the one that was the worst and leaking. Looked good on the outside but the inside is disintegrating and not watertight anymore. Chessie4905 has offered to check his parts bus to see what he's got, so maybe that will get me a little time to find a new one.
