Another advantage is when the laser craps out, the replacement part will
be $2,125, and that doesn't include installation.

I knew about Bosch but I had no idea Tesla was involved in the invention
of spark plugs. Thanks.


In many cases the term "laser" isn't always used accurately. High powered
LED's run through fiber optics and then exiting through a focusing lens can
create tremendous, pin point power. Similar to how we used to start fires
using sunlight through a magnifying glass when we were kids.

LED's and fiber optics are cheap. They are only expensive when the
application is on boats, replacing interior halogen light fixtures and when
you purchase them from West Marine.
