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:

heatshrink tubing

Yes, just not on the aluminum body so as not to block the air flow on the heatsink.

OK Thanks

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

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.

YES👍

I can't find it new from the factory.
