FORD DEARBORN (12/27/2020)
The Rapid flashing is only this flasher unit I picked up. The HD Ideal 536 that I took out it flashed what I felt was a proper speed for a old '50s car. The new flasher hyper flashes the first 4 or 5 flashes then it slows down flashing but it still flashes a bit faster than my old 536 flasher. The other thing is the 536 flasher didnt do that weird hyper flashing when you first turned the turnsignal on. It would start off flashing at the rate it remained flashing at. Its why I think these flashers I bought based off the part number may work in a '50s car but being a '62 design year it may be designed for different bulbs than what my '56 has which doesnt make much sense as I thought Ford always used 1157 bulbs for flashers. Only other thing I could think of is for the '62 design year they changed the flasher to make it cheaper or changed the flash rate but that doesnt make sense either as my 78 Mercury with the OE flasher had a slow flash rate even slower than what my '56 has with the 536 flasher that went out on me the other day.
I have to dig out my old supersede book to see if it happens to show this part number to get the original number but I dont think it has it as my book is from the time period when this revised number came out.
I will order a couple of those 552 Wagner's to give them a try as well. I actually got two Ideal 536 HD flashers on order NOS as well, one is a copper can like the one that I took out and the other is a silver can that is stamped "Mexico" on the plastic insulator and is obviously a newer production piece. Going to find something that works properly and will hopefully let me know when I have a bulb burned out. I dont want to use what I used in my other vehicles as they are all variable load flashers where they will flash the same rate no mater how many bulbs you have and Ive actually driven for probably a month not knowing a bulb was burned out cause the flasher just flashed the same regardless. Since that incident I been switching all my flashers back to OE flashers except for vehicles that I converted to LED bulbs, those I run the variable flasher still.
