Laser's can produce some serious light that can be focused easily. The downside is keeping them aligned in an off-road environment.
Baja Designs was working on them a couple years ago. Don't know if they still are or not.
That info has been on the site for a long time. Since they got bought buy Best top, it may be on hold. More than enough time has passed to get it going.
They had prototypes at SEMA and KOH. It is coming, my understanding is that Baja Designs has put the needs of the military market ahead of the recreational market at this time. But I expect laser technology to trickle down relatively quickly.
