It is more crisp and less likely to blind on coming traffic which is generally the biggest concern with LED xenon bulbs. The bulbs also give off a fantastic beam pattern which makes it better illuminating all parts of a dark road.

Heat Dissipation

As most modern LED bulbs have heat dissipation fins, the BEAMTECH guys made it super sleek and functional to disperse the heat without having to have a built in fan using aluminium. This is a huge benefit as the fans are known to become faulty over time and make a lot of whining noise when the lights are on.
