I was in the city and i seen a fixie with brake levers that clamped onto the tip of his bullhorn bars...they weren't inserted in but liek i said clamped around about a half inch down from the tip...where can i find these?

I believe they are TT brake levers.

Like these? https://www.pricepoint.com/popups/pop...20Zoom%20Image

those insert into the bullhorns...these levers didn't insert into the bars...

possibly talking about using hoods on a flip n chop?

nope...they weren't hoods

maybe old metal hood style levers.

My friend runs one.

he has it facing backwards and is positioned about the same place you mention.

cross-style interrupter levers?

On my fixie I have an RL-576. They look like this (this is a 720 as I run on my road bike):



I have it in the middle of my bullhorns, but similarly could be mounted at the end if I so desire.

Similar to what flimflam was saying, you're probably thinking of these:

Well, my friend doesn't those levers. His are old drop hood levers, put onto his chopped and flipped bars, reversed. I can't find a photo right now.
