so, is this a scam, or a worthwhile investment. I personally like to have as bright of headlights as humanly possible, while retaining my legality. If this really works, this would be very handy to me.
You'd have to check with your local authorities to see if multiple headlight use is legal in your area. In RI, it is not legal to operate multiple headlights, unless it is of the vehicle manufacturer design.
