ATV Lights Project

I am looking for lights for my ATV. Instead of buying overpriced lights in the store I thought I might build my own….sorta.

I’m thinking of using something like these XM-L U2 headlights

Then use something like this DC Car Power Supply Voltage Regulator Buck Converter mounted in a waterproof box to control the voltage going into the light from the aprox 14v that the ATV electrical system produces.

Any suggestions, thoughts or ideas on this little project?
