Pros: It works as advertised. It's very bright. I like having the extra lighting when in reverse.
Cons: The trail lights are way TOO bright. I expect everyone behind me will be asking me to turn them off. The only time they'll actually be useful will be when I'm dusting them. Further, while they look amber when they're off, they're really just a warm, low kelvin white when they're actually on. A darker, deeper, fully amber would be better.
To be honest, they look somewhat unfinished, like they need another lens to cover the whole thing.
I envision two paths to making this product better: 1) Version 2, correcting the aforementioned shortcomings, or 2) an optional, snap-on lens cover, amber and light-dispersing white, to make the amber dimmer and more amber and to diffuse the brake and reverse lights.
