So I have a couple things I want to do, one is install a PMW to my LED markers and running lights.

The other is how to make my marker light dim or turn off when turn signal is on?

Is a marker light a running light? Are they separate circuits?

Please define all your different "light" terms.

A labeled photograph would help.

"Markers are the ones that wrap around the corner aka parking or indicator lights."

So a marker is the same as indicator lights also????

For pwm one method is to use a 555 timer and mosfet transistor, are the marker lights indicators?
PWM has limited range with a single 555, the "elegant solution" uses 2 - or a 556.

A dual comparator can do the job with the same footprint as a single 555 - but it doesn't match the output capability.

A class-D audio chip might have the output capability to drive a bulb directly, but it could take a bit of searching datasheets to identify a chip that will tolerate the alternative use.
