Ignition Switch Harness?

Okay, when I am turning steering wheel quite a few degrees rapidly (e.g., to park), I notice that my DRL and headlights (times of day respectfully) will dim slightly and go back to full luminosity.

I am curious if this could be ignition switch harness issue or the steering system causing a power draw that dims the lights?

It's not a serious issue, but I am more curious than anything.

00 GT, 52,000 miles.

Thanks in advance.

Possible. A flaky ignition switch and harness does affect the DRL.
