vr,
Excellent stuff! And a homemade trunk! I wish I could sew (stop laughing you guys). I want to make a hood for my rear light setup and waterproof cozy for my battery box. (OK, NOW you can laugh.) Actually, I want them more for camouflage during my day rides than for water resistance. All the electicals are sufficiently weather resistant.

Somewhere in the back of my mind has been to rig turn signals and brake lights. Where can you get the Euro Clip switch? BTW, unless the switch gets hot, I would just slip a baggie over it held in place with a rubber band. That will keep the rain off of it and still allow you to see the buttons. Do the red buttons glow so you can see them in the dark?

This morning a couple of roadies I have gotten to know through occasional early morning encounters caught up with me, joking "Damn, somebody would need sunglasses to ride behind those lights!" I said "Yeah, but you saw me, didn't you? AND I don't ride this bike in a paceline." Besides, what they don't know is that these taillights pale compared to the one I will be adding soon.
