I have marked all my outside use tools with reflective tape. There are several different brands of tape that are routinely available at the big box stores; Scotchlite and Reflexite, just to name a couple. The tape in addition to bright colored paint greatly increases visibility, especially if you have a moderate to high powered flashlight. Hint: if you know any graphics shop employees, they might give you their scraps, FREE. Thats where I get 99.5% of mine. YMMV.
