Trux projector headlight assembly

I've gone through 3 pair in the last 2 years. They're currently on sale at Raney's. That said, with the Volvo ones, everyone keeps saying the bright and regular lights are backwards. They aren't! You need to adjust the lens with a 4.5mm socket I believe. They keep getting replaced because the wiring inside keeps breaking. Or the housing the lights sit on breaks. 1 or the other each time. Then again, I've had that problem with any headlights I've had. Has anyone else had this problem?
