66 Hazard Flasher Units

[Peter L.]

Looking for information on the stampings on the top plate of SIGNAL-STAT Hazard Flasher Units. I have 2 Chevrolet Hazard Switch Units that are supposed to be for 66 CORVETTE. Both are in CHEVROLET boxes. One has the Part Number 986639 and the other box is missing the ends with the P/N. The application listed in the Parts Catalog for P/N 986639 is 66 PASS, CORVETTE, G-10 (Van) and the box also indicates All Passenger Models - G-10. Both of these units are embossed FLARESTAT MODEL NO. 105 and stamped Y114. The unit in the box w/o a P/N has an Instruction Sheet, titles "TRAFFIC HAZARD LAMP SWITCH & FLASHER INSTRUCTION SHEET CHEVROLET-CHEVELLE-CHEVY-CORVAIR-CORVETTE- TRUCK G10 and the bottom of the page reads PART NO. P/N 3886945, SHEET 1, 7-12-65

I have 2 other USED units that I don't know what they are supposed to be for. One is embossed FLARESTAT MODEL NO. 105 and stamped Y113 and the other is embossed FLARESTAT MODEL NO. 105 and stamped Y133.

Does anyone know what the stamped Y number designation means? Is it a manufacturing or production code number?

The wiring on all 4 units looks to be the same, so I don't know what the differences in the units are, aside of the difference in the Y numbers.

Inquiring minds want to know. Pete

Hi Pete,

This won't do you any instant good as I'm away from my parts while here in Miami. When I return to Maryland later this month, I'll dig out my original and take some close-ups and send them to you. It's off the car now.

Meanwhile.....Calling Mark Nagy. Mark, I know you know your stuff here. Why don't you chime in?

Pete,

I can not answer your question but there is a Signal Stat Flarestat Model No. 105 Y128 switch currently listed on Ebay auction # 250753686049.

By the way, do these switches use a Signal-Stat 170 flasher (GM # 3843741 discontinued April 1967) with yellow/gold like finish?

David,

Yes, I'm pretty sure the #170 is correct. Rectangle in shape and goldish in color.

I had a heck of a time finding one.

Mike,

I had a "gold" NOS Signal-Stat 170 flasher on Ebay last week dated "S086" (8th week of 1966) but it did not sell. I guess the $40 price was too much for the current Corvette world.

Pete,

There is also a Flarestat Model No. 105 Y133 on Ebay (auction # 290522482764) from a 1966 Chevrolet.
