Welcome from Austria.

For led bulbs get quality ones. You will need a electronic/zero load flasher for your blinkers and hazard flasher when usind leds.
Hope that helps.
The only thing to note, you cant use LED in your Sidemarker on the fender unless you get creative to fix the behavior. Normally they come on with park lamps, and they blink opposed to the turn signal in front if you have the park lamp on
But without park lamps on, they blink with the turn signal
If you use LED 194, you can only have one or the other (by flipping the bulb around)
If you want to keep the switchback functionality, may need to use a module
if you want to install 194 in the sidemarker, and have them work as sidemarkers without other behavior , you can remove the wire running to the turn signal switch, and run it to ground. Then the other wire remains powered by the headlight switch.
I did this on my gmt800, but not for LED. My sidemarkers were nonfunctional entirely because i had voltage always on the turnsignal side. but thats not a common issue in the squares.
the rear sidemarker doesnt blink with the turn, so its not a concern
