Red light is commonly used in low-light settings to help users maintain dark adaptation, but results depend on brightness, exposure and the task. Follow the relevant operating guidance for your activity.

No. A filter changes light from a white source, while a dedicated red LED emits red light directly. The product manual explains which system the headlamp uses.

Petzl models and features vary. Check the current official product pages and manual for a specific model rather than assuming the whole range includes a red mode or filter.
