My jury's still out on these, but for $25 at Wal-Mart I couldn't resist giving them a try. Since I live in the North and it's light 'til late, I won't be using them that often, and couldn't bring myself to pay $250 for the really nice-looking PIAAs and another $60+ for nice-looking mounts. They're the 1038s on this page:
I used stainless steel angle brackets which I cut short and drilled out to accommodate the stock fender bolt, and the used the (rather large) mounting plates that came with the lights. I put them upright rather than hanging them so that the lights hide the mounting hardware somewhat. Had a devil of a time finding any kind of black plastic tubing that I could use to both hide and protect the bright green and blue wiring that came with the light kit, so I ended up using 3/8" corrugated wire tubing. Not sure if I like the look... The flash really highlights everything, I don't think it stands out quite so much in normal daylight.
I wired the power into the bottom of the fuse block, tapping into the supply side of the low-beams. That provides power to the foglights when low-beams are on, but automatically cuts the foglights off when high-beams are on. It also makes sure I can't leave the foglights powered on when I shut off the ignition!
I looked for hours trying to find a better switch or housing to use, but couldn't find anything that seemed quite right. So I pulled the lighted rocker switch supplied with the kit from it's faceplate, wrapped it in shrink-wrap tape, and used outdoor mounting tape to stick it under my horn button.
The lights work pretty well, certainly lighting up the sides of the road and better filling in the near distance. But I'd be glad for any suggestions on improving the appearance, mounts and/or switch system.
