Way too expensive. But, I acknowledge, looks clean
The housing itself looks to me to be similar to Optilux series, which work well and are (I think) in $80 range. You can also get the excellent Hella Micro DE for about $100 a pair (I just sold a pair to an inmate here for about $60, without wiring kit).
I bought these from eBay:
I dry-tested them, shining onto garage door against other lamps and they are fairly decent, especially in their role as a conspicuity light. I took a lot of comparison shots and will post later.
PIAA has a clamp bar mount similar to what the other lights have, about $40.
