You are one educated olbull....! Man...you are not kidding on the Chinese rip offs on the Daymakers!
I see a bunch of OPPO brands and others on Amazon. At least you got the real deal! They are pricey but if you do any night time riding those Halfords are a one way ticket to the morgue!
I ride in the day...night scares me....so I am looking for conspicuity first and illumination in the dusk hours when I am rushing home to the wife late from a liason with my hooker or coke dealer
