In another post, there were questions posed about adding strobing or flashing lights to the rear of a Pinz to make it more visible at night. As I HATE messing with electrical matters, I sought out a battery powered magnetic mount light that I found at a local company that sells emergency lighting to contractors, police etc. This one resembles a rear light that you'd mount to a bicycle seat post except that it's like 15X as big. Cost was less than $25!
The attached photos also show the "conspicuity" material that I added to the rear of the Pinz as well as the rearward facing surfaces of the forward most rollbar. As the truck is white, this silver tape is barely visible during the day but really lights up at night.
Bottom line, a slow Pinz during the day is fine but a slow Pinz at night is i-n-v-i-s-i-b-l-e!
And a real word it is, I too had my doubts.
