the solution is not 'buy a new light' it's to mount the light elsewhere.

since you're only using it to be seen i would do one of two things.

you can (seen this done and love it because it looks clean and prevents theft) take the bars off and put the loop of the skink through the stem, then put the bars back on and mount the skink around the stem/bar joint in front of the stem's bar cap. you can't take the light off without taking the bars off, but neither can passersby.

alternatively, you can just put it on the steerer tube/spacers. it looks like there's plenty of room for it, it will still be very visible to drivers and other road users, and it keeps the lamp away from your hands. a fork might hold it if you can't stretch it over the spacers but your other options all involve buying extra stuff or different lamps, which is not really a solution to your problem.
