Fender side marker replacement (smoked) opinions...

[Cadesto]

And my thoughts on side marker lights is this.. They are meant for people on the side and behind you to see your lane change.. The front blinker is for front light indication.. And 3 leds have gotta be brighter than one little dinky halogen.

Correct, the lights on the side fender (also known as repeaters) are to notify drivers who may be coming up along side and have already passed the rear turn signal, or have it blocked by the passenger side A-pillar.

The second part regarding brightness is sort of misguided.....that "dinky halogen" will have a higher overall brightness across the lateral plane (appear in a more consistent brightness level to an upcoming driver) than an led side marker because although the led is more intense, they have a rather narrow spread.
