Solid State (LED) or 552 Flasher?

This comment from Everett#2390 got me thinking about this again...

"However, if going to LED, use a 552 flasher as it does not care about current drawn as a 512 flasher does to flash"

I remember back in my RV tech days that we would replace the factory flasher with a "heavy duty" flasher when we wired a vehicle for a trailer to keep the flash rate at a normal speed. It's internally wired so it has it's own load to sense, regardless of the bulb load. The heavy duty we used must have been the 552. I always wondered if this would work for LED lights but never tried it.

If that's the case why all the hubbub of going with an electronic flasher???

Re: Solid State (LED) or 552 Flasher?

Thank you, Larry.
Why not try one and find out?
I suggest the 552 because its cheap and plentiful and easy to interface.

Re: Solid State (LED) or 552 Flasher?

LED bulbs use a much lower draw than filiment type bulbs. If an LED bulb is used in the turn signal circuit, the standard flasher will make the LED bulb flash rapidly. Using a flasher designed for lower draw LED bulbs will work with LED or filiment type bulbs. Best of both worlds.

Never argue with an idiot; they'll only drag you down to their level, then beat you with experience.
