I'm pretty sure I can't get my Cateye directly onto the rack mount. The piece of plastic which slides into the clip is not removable from the light like I've seen on some other lights. (BTW it is useless to slide the light onto the strap on the back of my seatbag, it falls out with any little bump)


I looked closer and I can see the model is Cateye TL-LD170. I gots no nubbins on the back. I also bought mine at my local Performance, I think it was $10, if it wasn't the cheapest blinkie in the store, it was certainly the cheapest Cateye blinkie.
