Some of the few MH cobrahead FCO's I have seen, and it's dayburning, so yeah. I don't see MH cobraheads that often. This whole intersection has them, you can see two others in this picture.
This would be PSMH though since MH doesn't exist for wattages under 175 (besides a 150W probe start MH lamp designed to retrofit onto 175W MH ballasts, which i think is no longer made). I don't see any PSMH cobraheads on public roads here. In Massachusetts along I-93 going towards NH there are 100W PSMH M-250R2 FCOs and OVHs. They give off a nice light. there are some ( i think 50w PSMH) M-250R2s near Mount Monadnock in souther NH too, though those are virtually useless.
Only place I've seen them is in a single parking-lot.
