LED blinker hyper flash

So I’ve bought some LED blinkers for my bike, completely forgot about needing something for the hyper flash. I understand the whole concept of it and all but one thing I’m unclear of is do I need a resistor ? Or a blinker led relay ? And do I need one per blinker or will one run all four blinkers ?
 
One resistor per side in parallel (that increases the load to make the flasher take longer)

OR

Swap the relay.

There are some pretty expensive options out there. And ways to do it cheap.
 
Yeah, I had this issue with my wife's Spyder - even the old ones apparently had monitoring circuitry, and it's common on many bikes now.

Though, a resistor oddly enough didn't fix it. Turns out that you need just the right resistor on some bikes as too much draw is treated the same as too little draw, throwing a fault resulting in hyperflash, or a fault light. Since I wasn't going to spend a bunch of time trying all sizes of different resistors, and from some cursory reading at the time finding out that the flasher relay was burried somewhere where it was going to be a half day project to replace it, I just put the incandescent bulbs back in.

I replaced the bulbs in my old VTX and the flasher swap took 30 seconds, problem fixed.

Swap the relay. $2 solution.

Well this is for my 08 Suzuki s40, and I ordered some blinkers from Amazon. Not exactly sure what route I should go for resistor or relay 🤷‍♂️

This is the blinkers I bought from Amazon
If they are not visible from the side you are in vialation of the Federal rule of vehicles in Canada requiring illuminated side markers.
 
Almost always. The exception is if your bike has a body computer that looks for current draw on your signal circuits. Not many bikes have this, most use a 2 post flasher.

A standard flasher relay heats up and fires off and on at the resistance of a signal bulb. A digital flasher has a solid state timer, it doesn’t care about the resistance of the bulbs.

Except when on many newer bikes the flasher is not a standardized flasher module anymore, but increasingly quite often proprietary. Here's a few of the oddballs out there now.

In general aftermarket LED happy modules do exist but they're not $2, and not something you can grab at Canadian tire.

See above. Lots of bikes have detection circuits now for burned out bulbs, although increasingly many bikes are coming with LED signals by default now anyways.

$12 on Amazon for a digital flasher. I bought a 6 pack off aliexpress last year for $10.

For what bike? Again, not all bikes are the same, and when you get into some of the more complicated flashers for many of the newer bikes, they are not $10 for six of them.
 
My 1990 (model introduced in 1986) Yamaha FZR has the turn signal flash function built into a relay module with a bunch of other stuff. My 2004 Kawasaki has a simple dumb flasher relay. Fancier newer models are likely to have the lighting done through a multifunction control module.
