Looking for a true heavy duty flasher

[Texas Red]

I am Looking for a true "heavy duty" flasher unit for my 72 Duster blinker system and my emergency flasher system ...... I installed a IDIDIT column and the cheap flasher units flash at such a rate they are not acceptable nor do they even look like anything of past yester years (looking at the taillights) .......This is something that used to be found at a junk yard crawl out of one ton trucks and the likes and is still on my mental list of things to look for on my next trip. They used to sell a true "Heavy duty flasher" at most auto parts but according to my Napa parts man they more geared towards the electronic type. I even bought one he said was a heavy duty unit to no avail........Please advise Texas Red

No such thing as HD anymore. I frequent the wrecker and pull flashers from older cars.

What feature are you looking for? Heavy Duty to me would be something with a high duty cycle, like a tow truck, garbage truck or school bus would use. I seen fast, slow, quiet, noisy....

If you are looking for the type of electro-mechanical that would have been installed in the 60s-70s to replace the original same style for heavy duty load applications such as trailer lights, look for old stock of #536. This is the longer, heavy duty version of #552 that was installed in most of the Chrysler cars then and will operate as expected with true incandescent lamp loads. The most commonly used brand to look for is Ideal. Other brands include Tung-Sol, Sylvania, Echlin(NAPA), Signal-Stat, Wagner, Buss, LittelFuse, etc. All will use the number 536, or a variation of it with extra letters. Anything by these brands (that remain) or others made in the last 10-20 years may not be the old style even with the same number.

The following image shows the 536 flasher:

The standard 552 was also offered as "H.D." or "Heavy Duty" in the short can package, but it's not a true heavy duty like the #536, just a bit heavier load capacity than the standard 552:

For an extra heavy duty electro-mechanical flasher, look for a Tung-Sol 852/5:

There is an eBay listing of eight NOS Ideal 536 flashers at:

There also, over the years, have been specialized, expensive, truck duty flashers, some electronic. I don't remember who made them, maybe Grote, Trucklite. I don't think KD lamp made one. I vaguely remember some in a clear plastic housing.
