V74 1966 hazard warning switch

[Ed M.]

I have a 66 427/390 coupe that I bought a few years ago that was a failed project (read many boxes of NOS parts and lots of junk). The car was originally a V74 car and I have found 2 hazard warning switches. The one I think is correct is configured the same as the one in Noland's book on page 373. When I searched the archives, the actual flasher itself seemed different. Here's what I have: On the main body top line is "FLARESTAT MODEL NO. 105Y133", the middle line says "SIGNAL - STAT," and the bottom line says "NEW YORK - TORONTO" and below that "one or more u.s. pat.nos. 2,652,553 2,692,981 2,607,840. The knob is a translucent dark red with grooves on the backside flange. The flasher is purple metal SIGNAL-STAT 146 4 LAMP LL. The wiring configuration is the same as the AIM and it appears to have original black harness tape on it. Does anybody know what I have? Thanks for reading.

Everything sounds like it matches my original one, except for the flasher. Attached is a picture of the flasher.

Bob,

Thank you, I was pretty sure it was correct. I'll have to see if I can find the correct flasher.

Ed - Signal-Stat made the hazard flasher switch units and I would expect the flasher for the 66 Corvette to be the Signal-Stat flasher w/ a gold anodized cover embossed on the top SIGNAL-STAT 170 as shown in the photo Bob sent. Pete

I've seen old stock V74 flashers in their GM boxes that were equipped with SS 175 flashers... These were NOT factory originals, but service spare assy's and the 175 flashers were the later era style with silver case and green silk screen ID for what it's worth.

Jack - I've seen both the 170 and the 175 (as you note)in the V74 hazard lamp switches being sold, but the part number in the 66 AIM is not the GM part number for the 175. If the hazard flasher switch was to be used on the 4-lamp system the 170 was usually used and if it was to be used on the 6-lamp or more lamp system the 175 was typically used. Having said that both flashers are "variable load" flashers and will work equally well with the 4 and 6 lamp systems; but as I said usually the 170 was used with the 4-lamp systems and the 175 was used with the 6 or more lamp systems.
