ST170 fogs are hella expensive. I was thinking about doing projector fogs today, but I wasn't sure if the bumper hole was big enough. I was gonna use Blazer projector fogs ($30), cut a hole and mount them, and maybe vacuum form a shroud or use the front half of the ES300 casing since it has this plastic lens to protect the projector.
There's some on ebay, but you have to watch which ones you get. The real blazer projector fogs take 880 bulbs, which is the same as ours, so that's a plus!
