Cateye 리어 랙/바스켓 라이트 마운트 (5342250)

After mounting it on my rear rack, I can finally see my taillight clearly over my panniers. The bracket feels solid and hasn't budged even on bumpy roads.

Finally, a mount that actually holds my light securely on the back of my pannier rack. The metal bracket is solid and doesn't wobble, even on bumpy roads. It solved the problem of my rear light being hidden behind my basket.

It does exactly what it says—gives a secure mounting point for the light on the rack—but the plastic feels a bit flimsy for the price. Took some fiddling to get it tight enough without worrying it’d crack. Works fine for my commuter, though.
