ortlieb reflectors - wet weather

i'm not sure if i should post this in A&S, commuting, or touring... i'm posting it here in commuting. feel free to cross-pollinate as needed.

i love my ortlieb bags, and part of that love is the nice big reflective patches on the fronts and backs of those bags. great stuff, unless it's raining.

just something to know about...


Ortlieb reflective patches - wet & dry

A pair of Ortlieb back-roller bags, with reflective patches lit by camera flash. The reflective patch on the left had some water splashed on it. The patch on the right is dry. The lighter spots on the left patch are were the water is beading off. In a steady rain these reflective patches would be rendered non-reflective.

essentially, the laws of physics (light refraction) at work. The same happens with all reflectors. Good to use abundant blinker lights

@sdvictor - NOT all reflectors do this. the DOT reflectors on trucks are a good example of all-weather reflectors.

i forget where i heard about it, but i think it has to do with the micro-surface of the reflective material being exposed to water, and basically the water fills in the micro-pores and turns the reflector into a non-reflector. i think the rule of thumb here is that reflectors that feels like very fine sandpaper will do this, and reflectors that are under a smooth plastic/glass finish won't have this problem.

I can't remember who advised it first, but try riveting a DOT style reflector to your fender. You can get a package of two stick-on reflectors made for mailboxes, driveways, etc. for about $2-3.

And check your blinkies work when wet.
