So I have some recommended rear blinkies for a Dahon rear rack. Thank you all.
Now how about the front? Can anyone recommend something that doesn't interfere with the handlebar folding function of a Dahon? The handlebar on my bike folds "into the frame fold", meaning I rotate the handlebars proper so the brake levers are vertical, and then the stem folds down against the front wheel, and then it all gets sandwiched between the two wheels when the frame gets folded.
It seems most of the good front blinkies am seeing are mounted horizontally on the top of the handlebar pointing forward, and are large enough that they'd interfere with the fold.
Thanks for the suggestions.
