Mod to make side marker and turn signal blink together?
 

it seems that for some reason the PO or PPO or who knows decide to reverse the TS with Side marker lights.

it doesn't bother me but for extra safety, I would not mind having them both blink (so cars in front and pedestrians can see my intentions better)

I read there is a mod for that, doe anyone can point me to it?

can I just jump a new red wire from the TS bulb to the side marker (and remove the wire going to it)? is there any counter-argument to do that? i don't really see the point of parking lights honestly... I'm a motorcyclist so for me id always keep the headlights on no matter what...

That mod should work fine.
Euro cars do not have that side light but do have blinkers on the fenders behind the wheels.

I've heard that some RoW cars had the turnsignal mounted where the running light is so the turnsignal can be viewed from a large angle to the car. Sorta like the people on a side road can see the turnsignal flashing on the side of the car.

I did modify my car to make the sidemarker blink with the turnsignals. For sidemarker, I used one of my sidemarker boards which is basically a full turnsignal with dim/bright LEDs.

Here's how I did the mod. Basically grabbed the turnsignal wire at the turnsignal and ran a wire behind the bumper to the sidemarker.
