Can I wear a headlamp on Shabbos (that was turned on before Shabbos) as I need to walk in a dark area?
I don’t see why it would be a problem, especially if people can & do wear digital watches?
Answer:
In regards to carrying and moving the lamp indoors or in a place which has an Eruv (or on Yom Tov), please check out this link:
However, outdoors in a place without an Eruv, it will be considered carrying.
See in the following link below regarding carrying a watch outdoors on Shabbos. Even according to the minority position regarding wristwatches, a headlamp is certainly not considered a garment.
