Topic: Minnesota and Wisconsin turn signal indicator bulb color

[67gta289]

OK, I got your attention with the title.

I was looking for some bulb information in the 67 shop manual and I noticed a note (3) that indicates that the instrument panel illumination turn signal indicator bulbs are 1895G for the "States of Minnesota and Wisconsin".  Has anyone noticed or looked into this?  If so can you enlighten us?

Not sure why this is needed when there was a green opaque screen applied at the end of the light tube.

To do this at the factory would have required that instrument panels be configured properly for cars going to these states.  Since there was a "Twin City" DSO, but nothing for Wisconsin...and since a lot of Wisconsin population is closer to the Chicago DSO, it would pretty difficult to pull this off.

It's so cold up there they had to pick a "warmer" bulb (Probably a 3200K bulb).

Never been pulled over to have those bulbs checked. LOL  Normally I did something stupid. St Paul Mn

Was this something that was required for many years or only specific time periods

I only noticed it in the 67 shop manual - I don't have other years to check.

Not in 1966 Shop Manual.  I don't have the 68 or 69 manuals.

The G means it was coated green.  Seems redundant, but maybe those states required green bulbs.

Checked my Service manuals.  Neither 66 or 68 has that note.

Possibly it was more of a service requirement than a factory build requirement. 

I wonder how many other state requirements there were before smog devices entered the scene.

Just to add to the confusion, in the 1960-68 MPC, and in the 1965-72 MPC, only the 1964-66 Thunderbirds have the Minnesota and Wisconsin requirements for the green bulbs. No other Models have this notation. I guess that the 64-66 Thunderbirds were "green with envy".

A little more digging produced the following :

SHOP MANUALS

READY REFERENCE CATALOGS

FORD SPECIFICATION BOOKS

1967 - Shows 1895G for Econoline, Bronco, Thunderbird, Mercury Intermediates, Falcon, Fairlane and Mustang

1968 - No reference to Green Bulbs for MN & WI for any 1968 Models.

TECHNICAL SERVICE BULLETINS

August 1965 - December 1968 - In looking at each TSB during this period, there was no reference to Green Bulbs for MN & WI.

The only other thing that I have that I can think to check are Shop Tips from 1965 through 1967. I will go through them later.
