Hazard Flasher Number

[Martin N.]

Hey Guys-
Looking for a hazard flasher number (preferably) the short 3 number for "Tung-Sol" or "Wagner" for my 1974. I have a test unit that tells me I have a dead unit but it flashes way too fast to keep in place of the old unit. Thanks.

Re: Hazard Flasher Number

Marty - I'd expect the original Tung-Sol hazard flasher number to be the 552. I know the Wagner flasher used in many of the newer hazard warning systems is also a 552. It's one of the common variable-load flashers used in the hazard warning systems. Pete

Re: Hazard Flasher Number

Peter can you tell me if the 552 housing is metal or plastic? Also if the housing is either metal or plastic are both housings the color of a gold or copper shade?

Re: Hazard Flasher Number

Mike - All of the Tung-Sol 552 I have seen have a metal cover. The T-S 552s I am familiar with that were original for 67s thru the early 70s have had the natural metal "silvery" finish, but I have seen T-S 552s with the "copper" colored finish but I don't know when they were manufactured. Pete

Re: Hazard Flasher Number

From the '82 Parts & Accessories catalog, the hazard flasher that was provided to service ALL '66-82 Corvette applications was GM # 491391 and a Google search says that PN is still available if it's a service replacement part you're after.

From a factory original standpoint, the current JG book says the AIM listed three PN's (multiple approved suppliers) for the application with Tung-Sol and Ideal being two that were recognized. My hunch is the familiar Tung Sol 552 is one of these. So, you'd be looking for a 552 with DOT marks and it should be rather easy to find either used at a scrap yard or new from an auto parts store...

Marty,
From my experience I'm used to seeing 552's on 68-70 cars. Around the start of MY 71 production the hazard flasher went to #536. The copper #536 is a later replacement. I'm not familiar with 73 and up cars but my guess is they would be #536.

Re: Hazard Flasher Number

My May built 70 has a silver Ideal 536 flasher that is code dated 1970 that I believe is original to the car.

Re: Hazard Flasher Number

Here's the "dog" I've taken out of the car. From all the descriptions on this post it sounds like this is the original from the factory. I'll probably do as Jack suggested and hit the bone yard tomorrow. Thanks for all the input guys.

Re: Hazard Flasher Number

Hum, that's interesting...your 'original' was in a gold tone can. I have this vauge recollection that gold vs. silver finish was a means of distinction between aftermarket distribution channel and OEM channel. But, that's unverified...

Here is mine from my 1970:

Well it would be, but I have posted it already -- so you will have to search for it. I am done f'ing around with the swtupid restrictions on this board.

Re: Hazard Flasher Number

Marty - Looking at the production code (290) on the side of the flasher can, I'd suggest you're looking at a flasher manufactured in the 29th week of 1980 or 1990 because the 1970 production T-S flashers did not have DOT if I remember correctly. Also, depending on when Wagner bought T-S, a T-S flasher with a 1990 production date might not be possible because the flasher would have been a Wagner brand. My 1996 Impala has Waqner 323 and 552 flashers in it not Tung-Sol. Pete

Pat,
Just to add to the confusion I have a July built 1970 with a #552 that is dated correct for the car. I don't doubt that yours is original so 1970 may be a year of either/or.
I echo Jack's thoughts on the gold flasher. I believe they are some sort of over the counter replacement and have never seen one on an original car.
I've been judging interior's on 70-72 cars lately and the #536 hazard flasher for 71 and 72 seems correct.
At Gettysburg we saw a number of 70-72 cars with incorrect turn signal flashers. You need a #224 blue plactic for that application.

JACK-
Actually, the can is silver with a green painted band on it. My camera was just adjusting to the light on the desk. Maybe it's not an original afterwards.

Peter-
Interesting. I had no idea these things were date coded. If I get a chance I'll be going to the bone yard next day or two to see what if anything I can come up with. I'll pay paticular attention to what make, model and year of car I (hope) to get one from.
