I purchased the Xenon's a few months ago based on the original recommendations in this thread, and have been pretty pleased with everything. The output from the OE headlights and fogs IMO are almost dangerous at night in my 14' GT . The upgrade made it very close to the stock HID's in my Charger and Durango with color temperature and light output. In fact I was so happy with them, I purchased their reverse lights which increased visibility fairly well even with my vinyl tinted taillights. My wife is impressed how well the headlights work over the OE as well. She never cares much about my mods, but this one she approves of LOL!
I can't say the brights help much more over normal operation, but I don't use my brights in any vehicle anyway. I did have a couple of problems mounting the controllers in the engine bay as they slid around initially. But with a trip Lowes, I secured them with some double sided 3m tape and zip ties, no sliding around now.
I installed these back in October of last year, and they have been holding up great. The last few days we gotten quite cold for us here, actual temps have been in the -20's, with winchills near -50. Headlights had zero issues in the extreme cold, and it sits outside all the time and not parked in the garage like the other two are.
For anyone still looking around, I hope my experience with these have helped a little.
