4 Way Flasher Part No.

[Edward J.]

What Is The Part No. On A 1972 Coupe 4 Way Flasher ? Does 536 Sound Right.

Re: 4 Way Flasher Part No.

According to page 24 of The NCRS 1970-72 Corvette Technical Information Manual & Judging guide both flashers are #536. Originall ones were made by Ideal corp; Tung-sol; or signal stat and have a 3 number date code.
Hope this helps.

Unfortunately, that statement is NOt accurate. Aprevious thread on this subject contains the correct information.

Re: 4 Way Flasher Part No.

That's great to know--glad I consulted the judging manual.

Re: 4 Way Flasher Part No.

Better that you consulted this board. The two flashers that are the same are the Alarm and hazard flashers. The turn signal flasher is different than those other two.

Of course you could search for the previous discussion and we wouldn't have to go through this again.

Re: 4 Way Flasher Part No.

Correct would be:
1970
hazard flasher #552
turn signal #224

1971
hazard flasher #536
turn signal #224

Is this correct?

Thanks Paul

Re: 4 Way Flasher Part No.

My 1970 has hazard flasher #536 and turn signal that is a gold painted tin can. I can't get to it at the moment to read the number. Even if I couldget to it I probably couldn't read it.Oh BTW don't forget about date codes.

Re: 4 Way Flasher Part No.

Paul - GM usually had several suppliers for items like flashers, so I would hesitate to "specify" a particular flasher for a specific model year. For the 70 to 72 Corvettes I have seen "original" flashers manufactured by Ideal, Tung-Sol, and Signal-Stat.

Hazard Flashers would be "variable load" flashers. The Tung-Sol 552, Ideal 536, and Signal-Stat 175 have been observed.

Turn Signal Flashers would be "fixed load" flashers for 2 lamps. The Tung-Sol 224 and the Signal-Stat 144 have been observed and I'm sure the Ideal equivalent has been observed but I don't recall the number

Alarm Flashers would be "variable load" flashers. The Tung-Sol 552 and Ideal 536 have been observed but I don't recall having seen the Signal-Stat 175 used for this application but I don't know any reason why it would not or could not have been used.

Re: 4 Way Flasher Part No.

Also, Littlefuse came along as a TS supplier in this era and they had a # 224 flasher module too. The 1972 Corvette P&A catalog has a somewhat cryptic call out for 'LF 224' in the notes column pertaining to then current service replacement TS flashers which seems to say Littlefuse was an approved vendor, at least by 1972...

Re: 4 Way Flasher Part No.

I cannot speak to the Ideal or Sinal Stat flashers. However, the Tung Sol 4 way flasher is part number 552 and would be silver in color. If it is gold, it is an aftermarket replacement. How do I know this. I worked for Tung Sol during this time period.

[Terry M.]

Re: 4 Way Flasher Part No.

The Ideal hazard flasher is gold colored -- you can see it in the corner of the picture of the fuse box I posted above. That is the one the UAW installed in my 1970.

[George D.]

Re: 4 Way Flasher Part No.

I guess I wasn't specific enough. If the Tung Sol 552 is gold it is a replacement flasher.

[Terry M.]

Re: 4 Way Flasher Part No.

No confusion here, George. I understood what you meant. I just didn't want people to go off thinking gold hazard flashers were inappropriate.

I keep thinking of "big block half-shafts" which aren't exclusive to big blocks at all. It is too easy to take shortcuts in terminology and wind up with inaccurate expressions. Oh, add "radio delete" to the list too. I just don't want another malapropism added to the lexicon.

Re: 4 Way Flasher Part No.

For what it's worth... I was able to swap the light blue Tung-Sol #224 COVER from my non-working, but original, flasher to a new flasher from the parts store.
I only cut one finger a little bit (no stitches) getting them apart.
