Sounds like just an evil place to ride, no matter what. I'd go with a Dinotte (either the 300R or 400R) for the down range long view and then a Redzone 8 for the wide angle view. That ought to make you very visible.

The difference in effectiveness of the Dinotte 300R to 400R is probably not huge.

The ones to look at are the Nightflux Redzone, the Dinotte tail lights, Lupine's new tail light (Rotlicht).
