Hazard Flasher Number

Re: Hazard Flasher Number

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.

My original turn signal flasher is a gold tone. I had to rename it so you guys could see it --at least I think that will work -- well no renaming it won't work either. Why do the administrators make it so difficult to help other members?

Instead of searching you can look here and see that it (the turn signal) is gold tone, except where I have take it out so many times to satisfy the curious.

Interesting Dave. See mine below.

Dave or Pete, would you read the code as the 5th week of 70 (which would work for my May built car), or the 50th week of 70? Either way, it sure seems to be a 70 dated flasher and thus could be correct for some 70s. There's no DOT mark by the way.

Dave - Sorry I missed connecting up with you at Gettysburg. While I agree that the blue plastic Tung-Sol 224 is the flasher that appears to be more common in the turn signal systems of the 70s Corvettes, I have encountered quite a few owners of 70s Corvettes looking for Signal-Stat 144 flashers to replace the original Signal-Stat turn signal flashers in their cars. Most of the Corvette AIMs "call out" at least 2 turn signal and hazard flashers and some even show 3. Pete

Re: Hazard Flasher Number

Pat - The first 2 digits are the week of the year, i.e. the 5th; and the 3rd digit is the last digit of the year, i.e. 1970. The flasher is typical of the silver Ideal flasher with the black silk screened lettering of the late 60s & early 70s. It is my understanding that items like flashers did not have to have DOT initially on the items as long as the manufacturer could demonstrate or prove the item conformed to the DOT requirements. I have Ideal flashers in individual boxes with a slip of paper like what's in a fortune cookie that states that the flasher conforms to or meets DOT requirements. Later, I'm sure individual items needed to have the DOT logo on them. Pete

Pete,
Somehow I missed you as well. Great meet with lots to do.
Is the 144 a round flasher.??? As you know there is a clip on the backside of the passenger dash pad that is made to accept a round flasher. All blue plastic #224's are round.

Re: Hazard Flasher Clip

Dave - The Signal-Stat 144 turn signal flasher is rectangular. The clip is versatile. Pete

Pete,
I thought is was rectangular. I must admit I've never seen a rectangular flasher in that clip but we all have learned to never say never.

Re: Hazard Flasher Number

On the issue of 224 flashers, my experience from walking the scrap yards is that it's NOT unusual to find a GM car from the early 70's (Chevy's too) that look reasonably 'untouched' and have LittleFuse 224 flashers in the TS socket...

Complimenting that, the reprint of the 1972 Corvette Parts & Assessories Catalog that we used to sell via Cincinnatti, has an interesting comment! When you flip to the P&A section that covers TS flashers, there's a note accompanying the GM PN for the service part from this era that reads 'LF 224'...

I take that to mean that GMPD (predecessor to GMSO) recognized Littlefuse as making a legitimate 224 compatible flasher by late '71/early '72. So, as an interior judge I wouldn't deduct for the presence of a Littlefuse 224 flasher in these cars. There was quite a bit of other Littlefuse supplied electronic content back then that we DO recognize as factory correct/original like the TCS/CEC emissions relays...
