Not familiar with that particular rack - what I did on my commuter: purchased a cheap trailer reflector at an auto parts store and zip tied it to rear of rack. Using a pair of hose clamps, I clamped a length of pvc pipe across the top of the rack; a Dinotte tail light is on one side and a backup PBSF is on the other. Keeps the lights above the panniers I use. Cost was maybe $2 for the reflector as I had scrap PVC, zip ties, and hose clamps.
