Hella has them.
Are you looking for an amber lens or light that is amber. You can put an amber/yellow bulb behind a clear lens. Headlights & Fog Lights
They have H3 bulbs in multiple colors.
I like amber as well for fog usage, and replaced the bulbs in my stock lights with a set. Stayed with the standard 55W bulb, it's a direct replacement.
Side note: if anybody is looking for replacement lamp pigtails, connectors, sockets - take a look at the bottom of that page.
