I do not know where to add this piece of advice as it covers all of Spain and this in particular Galicia. An article was published in the newspaper La Voz de Galicia about a campaign to fine pedestrians who do not wear reflective jackets. http://www.lavozdegalicia.es/galicia/2011/10/03/0003_201110G3P4991.htm Although this law covers all of Spain; there seems to be more pedestrians killed in Galicia (per head of population) than in any other part of Spain. The nights are now drawing in which makes for a timely to start such a campaign. The two points on this law that particularly affect pilgrims are · When on a bike and lights are in use, cyclist are required to use reflective clothing. · Outside the village, between sunset and sunrise or weather conditions that reduce visibility significantly, all pedestrian, should use reflective jackets. If you have support drivers they also need jackets in the vehicles for use when exiting on country roads in all weathers and times of the day. all reflective equipment should comply with EN 471, It basically states that the wearer is visible from a minimum distance of 150 metres.
