He has a Luxeon Star Portable 5.6W white tail-light too. (Might be
prohibitively expensive for many, tho'. These Luxeon's aren't cheap!)

Actually, a 3w luxeon is less than $20 -- more than enough for any tail
light. The other $130 goes to the guy. Get a surplus housing and drop
in an LED!

(Also no financial interest).
