My Cateye 3 led head lights work great, good quality, small,,yes I got two,,for a total of 6 Led's.

They are not very powerful but they work for me.
they each came with a 3 led tail light,,so I also got 6 led's out back,,

Both Kits cost together the same as the ONE head light the OP found on Ebay
and the Batteries last along time,,80 hours full on up front,,,320 out back.
