That's a tall order. I've seen sets on e-bay go for $450 so even if you find some, you're going to pay an exhorbetant price. Michael Terry sells replacement bulbs and now I notice he also has the rubber housings.

Luckily I got mine before Honda discontinued them, and my second Valk already had them on there when I bought it (definately was a factor in my purchase). I love the fog lights on Interstates but I doubt I'd give market price for a set.
