I've seen a few of the cheap China knock offs for the PSD's, and they're total junk. Wiring is tiny, plastic is thin and very poorly formed. I tend to stay with stuff that's OEM replacement, like DEPO's offerings for headlamps.
I ordered a set of DEPO's factory replacement '05-07 Harley Headlamps for my '99, and after some cutting of the grille support (Your factory lights WILL NOT be able to re-install if you do a '05 headlamp swap), and changing my headlight plug from a 9007 to an H13, they worked beautifully and had a TON more light thanks to the clear lens and improved reflectors.
They use existing holes to bolt to (2 on the top that were never used prior, and the bottom 2 that held the signal lamp assembly in) and are totally worth the $280 CDN I spent to get all the parts.
I did all the cutting and installation myself, it's pretty straightforward, just make sure to wear a mask when cutting, as the grille support is fibreglass, which isn't fun to breathe in.
Any questions PM me, I'd be more than happy to take some photos of my lights and how/where to cut if you decide to go the '05 lamp route.
