You just got suited up for your first dive of your vacation in St. Somewhere. You test either your camera system or PCa Lite one last time before taking the plunge, and your flashlight or Strobe aiming light won't work. The worst thing that can happen on a holiday dive, malfunctioning equipment and you don't have aspare bulb.
Don't go on a trip without spares. Make sure you have a replacement flashlight or modeling lamp for your PCa Lite or Substrobe 200, 150, 225, 300, 400 7.2V 0.8A . Bulb is a 7.2 volt, 7.2 watts halogen lamp and makes a great item for your Save-A-Dive Kit.
