    I noticed tonight that my headlights dim or pulsate when VSC kicks in (slip indicator comes on and blinks in dash) on my 2020 Sport MT. Should I start looking into it or is this a common thing?

    It does happen at low speed (and of course low RPM) plus I have upgraded headlight (h9).

    The VSC is probably cutting engine power and the low rpm’s cause the dimming.

    Mine does it too. I assume it's normal.
