Need help with relay part numbers and Lg fuse specs (2023 CX-5)

Hello friend, how are you? Do you think you can help me with the relay? I have a Mazda CX 5 Active which comes with basic headlights without daytime running lights. However, I bought a used original headlight and it is full LED with daytime running light. But when I installed it I realized that it flashes too fast when I turn on the turn signal of the headlight that I replaced with full LED, that is due to the relay, right? Do you know how I can locate it and if it can be replaced with a higher version relay?
Just spitballin', but....
I don't believe the relay is the problem. I have had several cars in the past where the inside turn signal indicator would flash rapidly as a notification that one of the turn signal lights was burned out. Nothing wrong with the relay, just a burned out bulb.
The issue with new cars is everything is computer controlled. You can't just bust out a VOM and follow the voltage to the failure point. The computer is in the way, controlling everything.
On newer cars, some folks that replace their incandescent signal lights with LED bulbs have the same fast flashing of the signal light. I suspect this is because the LED bulb uses a fraction of the current of an incandescent bulb, so the computer thinks the bulb is burned out, and goes into fast flash mode.
The solution for this issue is the installation of a resistor in series with the LED bulb, to draw a larger current load, to simulate the stock incandescent bulb.
I've never done this work before, so I would suggest doing some research on installing a resistor in-line to an LED bulb to prevent the rapid flashing turn signals.
I would also suggest starting a new thread, to get any additional assistance.
Good luck.

This is exactly correct. The standard method is to use a 6ohm 50watt resistor per bulb, and there are plenty of these available at different stores for this very reason
Not sure what's available in your country, but this is a representative set from Amazon in the US:
