HELLA’s Vision Plus conversion headlights adapt European technology to US lighting standards and driving conditions to produce superior headlight units that replace your dumpy, ineffective old 5 3/4 in. round or 146mm rectangular headlights. They produce the brightest, most powerful light possible–right at the legal limit–without increasing glare. More importantly, their precise optics produce a much longer, wider, larger, and better illuminated pool of light in front of your vehicle. You’ll love the improvement. In addition, they have replaceable bulbs so you don’t have to buy a whole new unit if one burns out.
