We have certainly beat the visibility vs safety to death. Please note the original smiley--as I keep saying, I am not doubting they make you more visible from the front, just making a small joke about oncoming traffic.

On the Amigo I sold, I put 1" reflective on the front skid plate and A-arms. From more than 10 feet away, it was an extra layer of reflection, if you want to try it. Plus, I picked an accenting color so it looked good, too. Having it on 31.5" tires might have made the underbody more visible, however, in the dark I can't tell if it would work on your vehicle.

Thanks for the name, I looked it up. They make quite a variety, from unit-controlled kits to simple plug-in bulbs.

In my "little bicycle light" (aka diving light) defense, the actual bulb size is a little smaller, but the bigger boost probably comes from power driving the light (one Whelen 4-way strobe kit was 90 watts--much less than an AA battery!) Things such as capacitor charge and flash time also come into play. The diving light is only about once per second, much less than a Whelen box that claims,

Either way, the dive light is visible from 3 miles away (per advertisement). Unless you're on the salt flats, that should be good enough for roadside safety use, and as a bonus I can take it with me on dives, bike rides, or motorcycle trips. As a thought, since you're into safety, you might pick up one or two--what would you do if your electrical system is what blew? You couldn't power the lights. But a safety AA powered backup would be handy. Just a thought.
