Headlights Dim When Gear Changes

[TimJohans]

Hello there,

I have an automatic DS3 120vti. When the car changes gear, the headlights seem/appear to dim slightly before returning to normal. The car is a mid 2012 model, and has done approx. 15K miles. Could this be a battery related issue?

Seems the most likely explanation, as I can't see how they can be related otherwise. The battery is well known for causing some weird faults when on its way out.
