Electrical: Lark Map Light is broken

[creegster]

While trying to replace the bulb in my 59 Lark dome/map light, it appears that the bulb backing piece has broken.
Do I need to replace the whole unit, or is there a fix for this?
I guess I could try to make a replacement piece out of plastic, not sure how well that will go...

Any suggestions?

Dorman has one found at Rockauto should be able at any auto parts store

In a pinch I've even made such a piece from an old circuit board after I removed the copper.

That interchanges with many other years. I'd replace it so it does not sort out down the road.

Look what I found at Autozone. Sweet!

Unless I'm missing something, you need to take that one back and exchange it for a "single" filament bulb. The one you show here looks perfect for a double element bulb, but not a map/dome light.

The broken one in the original post is a dual contact insulator. Had me puzzled too, but it has 2 contact holes but only one wire and contact.

This looks right to me: the original was a double-filament as well. IE, it has 2 contacts on the base of the bulb. Some parts shot out of the housing when I was working on it, and I dont know where they went, so they are not in the original photo.

The bulb may use one filament for the switched power at the light housing and the other filament for the door switches.

Double contacts does seem strange, and I'd look at the wiring schematic to see what they show.

As per the Owner's Guide, they use a 1004 bulb, which is double-filament. https://www.autozone.com/electrical-.../16805_0_18269

Thanks for the clarification...a good thing to remember...'till I forget...again

There was a time when you would see scads of these late model "used" dome lights, including the cover and lens, for a buck or two at Studebaker swap meets.

There are single filament with dual contact bulbs for a variety of applications where the assembly is not used as a ground where one of the wires is connected to ground. I have wired some lighting this way to assure a good ground. This type of assembly is used in marine applications where the body is fiberglass where there is no continuous ground. This also works well around rusty tail lights and anywhere where a good grounds are questionable.

Studebaker actually sold those 'fiber discs' as a repair item. We have a bin tray full of single wire types.... Not sure If we have a disc for two wires or how many.

Anyone need single wire discs?


Now days a good dome assy is 20 bucks in good condition. (evil vendors! )
