Everyone knows that you should add reflective tape to your gear and to your equipment to make it easier for other boaters to see you and for the Coasties to rescue you.
One of my Christmas presents that I received was a Pro-Tec helmet. Of course, I wanted to add reflective tape, but I didn't want to end up looking like a safety dork or like a Coast Guard Wannabe. So, I picked up some black reflective engineer's tape. In normal light, the tape looks like black electrical tpe. But, when you shine a light on it, it reflects back a bright white.
Definitely a safety dork. Note that this pic was taken with a flash, with no tape on the helmet.

Same helmet, same black tape, only this time taken with a flash:
Note that you can get Engineer's tape in a number of different colors, so you add reflective safety tape to your helmet without fear of looking like a safety dork.
