BEAMTECH Hi/Low 50W 8000Lm 6500K Headlight Bulbs

Brightness
The BEAMTECH bulbs give of a 6500k white xenon light which personally speaking is a huge improvement over any bulbs such as halogen or lights that give off higher kelvins.
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.

With stress tests proving the lights can last over 30k hours, you can be sure that these bulbs will keep going for a long time. With the added bonus of the bulbs being waterproof with a level of IP65, these bulbs can last extreme conditions.
Also something to note is that the power usage of these BEAMTECH bulbs is only 25W. Making your battery last longer.
