Easiest Mini-Mod ever, and it results in a noticeable change. I simply purchased a set of small reflectors for $1.99 at an Auto Part store, cut it in half, and stuck them on my rear lower control arm. I wiped it off with alcohol first so that it would stick, and applied pressure. They've been on for almost a year now with now problems. The best results are when your driving at night on the freeway. Drivers behind you will see both reflectors illuminated almost as bright as a LED lights.
If you notice, most new SUV's will have low, horizontal reflectors or lights on the bumpers creating the effect of a taller vehicle when viewing from the rear similar to lower valence fog lights from the front (ie. New Toyota Highlander). This does the same thing. Try it, you'll be surprised at the results when you drive behind it.
