Portland Design Works Gravity Plus Tail Light (Black)
A single rainy ride trashed this light. Inner light was half full of water...likely never a good thing around circuit boards, etc. Failed to charge or turn on subsequent to this. Will be reaching out to PDW, but certainly would like to hear from performance as well, especially in light of the many good reviews this light has received.

Portland Design Works Gravity Plus Tail Light (Black)
Adequate tail light in flashing mode. Good "be seen" tail light. But top notch brake light function. Wireless, nothing to corrode. Very good for heavy traffic situations with cars. Got to be careful about tilting bike when parking . Brake light comes on unexpectedly. Flashing green light indicates time to recharge. Seems to be rain resistant when mounted under seat.
Rated 5 stars.
