A lot of "rice" cars use them, but it can be a way to improve your headlights to make them brighter, but really not needed.\n\nA good set of headlight bulbs shoudl be bright enough, especially if you upgrade to the sylvania silverstar/atravision bulbs

It's impossible to say considering you give no indication of your lighting needs.\n\nThey do make fourescent bulbs which fit into regular incandescent sockets.  The flourescent bulbs use a lot less energy.

If the deflection surface has any diffraction or diffusion to it, the light may just be redirected imperfectly. 12kV? Jumpin Gigawatts!

What you see are particles of dust in the air, illuminated by the projector's beam.

Halogens are quite yellow compared to the more modern lights of today(LED, ARC's) so while they may have seemed very bright ten years ago they have just aged a bit but are not any less efficient. You could upgrade the bulb if you want to although it would eat in to your running time.

i want to make a system that gets mounter to the passenger front bumber of my car, so when im stuck in traffic and some _hole feel he deserves to drive in the emergency lane, the laser will burst a hole in his tire, and give him a reason to be in the emergency lane.  Some issues with this system is the timing of when to fire the laser, how much power the laser would be.  You dont want to accidentally fire at the wrong thing, so these issues must be addressed first.  I think thats pretty innovative.\n\nwhilst working on my M.E. senior design project, my sponsor (an artist) wanted to make a dynamic hologram depicting a full COLOR rainbow..  Yeah, I know...  It made for great jokes the entire year.
