Today I put some white reflective tape front,

flashlight at it from ~1.5m makes for a very
visible reaction.

The only downside was that the tape gave the
impression of not really sticking to the bike.
On the casette saddle-stay side, I had to clean
the stay with acetone before it would stick
at all.

I put reflective tape on the frame and rims of the bike I used on Paris Brest Paris. It was some silvery white reflective tape. I covered the entire frame, except the headtube. And strips between every other spoke. When car headlights were shined on the bike, when driving into the garage, the bike lit up like a beacon. It was very noticeable when lights hit it. From any angle.
