I saw that it usual supplies at 25W, 50W 100W ...
So for my calculation I need:
WH50 7.5R 1%?
aluminum resistor is "WH"?
I have seen that it can be found in all sorts of names when the keyword "aluminum" is in everyone.
Is there a professional name for this component?
This is a 50mm long monster...

These are usually known as "aluminium housed wire wound resistors" or
"aluminium cased wire wound resistors"

Inside aluminum heat-sink is windings of wire with resistance like light-bulb filament. So basically to get LED bulb to work, you're attaching in parallel incandescent light-bulb that generates 100% heat and no light. :)

Here's how to install ballast-resistors in parallel with LED bulb.



Snip both wires of LED light so we have 4 free ends.


Re-attach each wire-end back to itself and around resistor terminal.


Finish with solder and heatshrink tubing and you're done! Simple! :)

Yes, and those who do not want to generate heat, or do not want to connect 4 power resistors, can switch to:
Electronic LED Flasher Relays for Motorcycle
heatshrink tubing
Yes, just not on the aluminum body so as not to block the air flow on the heatsink.

OK Thanks:)(y)

In the end, my relay-flasher was faulty. I replaced it and all works well.
Thanks for the update. This week I too had to solve a signal-lights problem. The left one started flashing faster. It turned out to be a bad electrical contact in the new signals I bought from AliExpress. While searching for a solution to the problem I noticed that in the American CBR model the relay-flasher is 9 pin, and in the European only 3 pin. The difference is seen in the schema found in Haynes' book. That's why you have the connection between the front and rear done in a your relay-flasher, so replacing it has solved the connection problem for you(y)

Awesome! Can you provide link to flasher relay? Would be great reference to others having similar issues in future.
I bought it used on ebay. I searched but I couldn't find a manufacturer that makes an aftermarket part and even searching now, I can't find it new from the factory. It's a special 9 pin device and it has plagued me for months. I'm glad it wasn't a wiring harness issue, I was seriously considering selling it if it was.
