I installed these on my canyon bars. Wicked bright, and seem to be made well. No problem with amperage on the accessory circuit (I don't wear heated gear, so no draw, other than my phone charger). The waterproof plugs that come with the lights made it easy to mount and button up. I've got them wired directly for the time being, waiting on a lighted switch to arrive.

Something worth noting - I could have gotten the extra lumens I was looking for with just an LED headlight upgrade, but my personal opinion is the more lights and the wider the light pattern on the bike, the easier it is for cars to see us. Seems motorists get confused by a single, really bright light. No spacing of the lights to judge distance, perhaps? Not sure. Some may differ, but my thinking is I'll be easier to see with this setup.
Anyway, I'm really pleased with the lights and mounts. I'll try to post some pics when I get a chance.
Be safe!
