Wig Wags are illegal in most places. Check your local laws.

I know they are, but 30% wigwag may be acceptable if the beam otherwise stays on.
This is one of those rare times I think the law needs protested.
Nobody has updated the car light science to match the airplane light science. Half hertz to two hertz blinks, flashes, or dims get attention, and they do not match the 18-40 flash per minute blink rates of the law enforcement/fire/warning lights.
My state seems to tolerate subtle blinks, and bike rear turn signals that would make a Knight Industries K2000 or a cylon warrior proud. I've seen some pickup trucks that tow trailers fitted with some wicked red aftermarket stuff. OK, wicked is not a good adverb to use on LPF, but you get my point.
The brake lights that stay mostly steady red and then flash black a few times at a perhaps 5% "off" duty cycle, at a rate proportional to acceleration really catch my eye while staying pretty close to legal.
Just my two cents, and I know I'm pushing it on the law, but using the 1960s DOT lighting scheme is getting lame in the year 2010.
However, I have a friend who does decorative lighting on his car show car who has been fined multiple times in PA, even with the harnesses disconnected in between shows. Because once your in their computer....
Just my opinion, but I think stylish LED tail lights on some production cars are getting far worse in beam shape and brightness then the standardized light designs they replaced.
I am the first to agree any blue or green up front is a no, no, and I hate the dyed or dielectric coated, overdriven halogen bulbs sold on Epay.

The pseudo wig in the video is nice and gets attention.
Remember, your subconscious system is looking for the slow motion of a predator coming to eat you, and that half hertz-two hertz is the frequency that corresponds to getting eaten. At least the peripheral vision is wired that way.
I can dig up a Navy study to back me up on the flash rates.
Cars got mandated high CHMSLs, what 15 years ago, why cant a bike have a safety boost.
I'll stop ranting now.
