Montgomery County police cars have and use wig-wag headlights.

It does seem dense, to say the least. I'm a Maryland resident, and can't
understand why something so effective should be unobtainable...legally,
anyway, since I do know of emergency vehicles (which shall remain
nameless) which have wig-wags.

That's because Montgomery County thinks of it's self as being above
the rest of the state.

In Massachusetts, wig-wags are legal on emergency apparatus,
but illegal on personal vehicles. There's a push to make them
legal, and many local cops won't issue a citation for them,
but there's been an uproar lately over people stopping for
wig-wags thinking it's the Police, and being assaulted.

Madebe PDs should not have class C or totally unmarked squads do traffic
stops. I Know that the department that I interned with will not allow officers
to pursi
purse or pull over people in their unmarked squads.

All the more reason not to stop for unmarked cars.
Stop only for red and blue full bars on top of the car.
I wont stop for anything less.
Have gotten bitched out a few times as a result.
Once I see a 2nd car pull up with lights tho, I usually stop.

In Connecticut it is illegal for ambulances to have them. I believe that it
is legal for police cars and fire apparatus. I know that most of them do
have wig-wags.

...you know what is amazing about this newsgroup?

Folks seem to fall all -over- each other to reply to notes about "light
bars" and "green dash lights" or "wig-wag headlights" ...but all too
often there is never a reply to technical or philosophical questions that
will profoundly effect our professions.

Not a condemnation - just an observation.

In a recent message by Daniel Misgen

Several PDs in the Twin Cities (I know of a few for sure I expect a lot more) no
longer
allow unmarked squads to effect traffic stops. The general rule of thumb seems
to be if
you think you are being pulled over by an unmarked proceed to the nearest PD or
'public'
place before you actually stop. I expect in the situation of a 'real stop' this
would be
defensible activity before a judge.

From a logical perspective, the effect of wig-wags can be achieved
through grill mounted strobes. Having driven many times at night with
wig-wags I know the changing lights can effect your field of vision. Do
away with wig-wags and use headlights for what they are intended - to see
at night - and use strobes or flashing lights for what they are intended
- to be seen by others. simple enough solution.

Given the number of incidents involving police impersonation, the
Massachusetts State Police are advising motorists

1) to stop for flashing lights only in well-lit areas if possible
2) if you have a cell phone, call *SP to verify the stop
3) to lock your doors and crack the window instead of rolling it down
4) if the officer isn't in full uniform, leave immediately and proceed
to a local police station or other populated area.

Only a local hothead wouldn't understand that reasoning.

wig-wag headlights have been used for years primarily to effect better recognition
of an emergency vehicle in DAYLIGHT. You are competing with 400,000 candelas of
sunlight with your emergency vehicle warning lights, so the brighter the source, the
better off your are WHEN THE SUN IS SHINING. Colored filters on both strobes and
incandescent lights considerably reduce the luminance/lumen ouput of the light
source, so anything you can do to increase luminance in daylight is good. HOWEVER,
at night, the story is different. There is far less need for wig-wag headlights,
and in fact, as was noted in the posting, they should be used for driving only.
Auxiliary flashing lights in the grill, overhead strobes, etc., are usually more
than sufficient to identify the vehicle as an emergency vehicle at night. Adverse
whether further complicates the matter due to absorption of the luminance by
precipitation. Again, in such cases, color is far less important that luminous
intensity. A 100,000 candlepower xenon strobe with no colored filter will be far
more visible than one with a red filter which is only emitting 20,000 candlepower or
less. This research was clearly demonstrated by the Minnesota Highway Department
study on effective emergency lighting for snowplows in extreme weather conditions.

Emergency Vehicles should be configured to have a DAY response mode, using
everything you can turn on, and a NIGHT response mode which is more conservative.
Remember that human neurophysiology of vision is very adaptable to ambient lighting
conditions, and when there is an absence of the strong light source provided by
sunlight, less is BETTER. As far as colors, go, considerable research has indicated
that blue works best at night because it contrasts against the normal colors seen in
traffic of red and white. Conversely, in daylight, RED works better because it
contrasts against the normally high concentration of sunlight which is very rich in
blue light. In any case the RED has to be VERY HIGH INTENSITY to effect a good
contrast. Otherwise, the yellow/green light of a tungsten halogen lamp source, or
the more spectrally balanced output of a xenon strobe WIHTOUT FILTERS is a good
choice in SUNLIGHT. Using red filters on xenon strobes is the least efficient way
to go, because xenon has very little red spectral output, and a lot of yellow,
green, blue and violet. Conversely, tungsten halogen, has a lot of red, yellow, some
green, very little blue and violet.

The National Institute for Standards and Technology, Department of Commerce, USA has
several well written documents on the efficacy of emergency vehicle warning lamp and
siren systems, detailing human neurophysiological responses to lighting and sound,
and recommending the most desirable approach to warning light systems. It is well
worth getting a copy from the government printing office to read. The real problem
is getting a nationa/international standard that is common to all countries so that
responses are based on standardized warning lamp systems instead of the "crazy
quilt" of regulations and configurations adopted by each state in the U.S. and many
international countries. Comments?

Actually... MI wreckers are required to have amber, but red is allowed as in

Last time I looked, the California VC permitted wig-wags only during daylight.

Too much emergency lighting makes turn signals & brake lights harder
to see at night.

In New Jersey, Wig-Wags are illegal. According to NJ Title 39:3-47 it
states that no person shall alter the performance of any light in a
way that it was intended. Wig Wags are an add-ons, therefore illegal
by this standard. It does state in 39:3-50d that special permits for
flashing lights can be issued, so it would seem that a permit would
have to be issued. I know many NJ fire, squad and police that are
using wig-wags. But remember use by many does not makew them legal. As
I look through the section of title 39 that covers emergency lights,
it never mentions flashing headlights as being permissable.

The section of the California Vehicle Code dealing with daylight
restrictions on wig-wag headlights was removed a number of years ago.

The other place to check for California "Code-3" vehicle requirements
is Title 13 of the California Code of Regulations (was the California
Administrative Code). (Is YOUR siren speaker legally mounted?)

I am not sure about the exact wording of the law but we were able to get
around this problem in our town (Vernon, CT) when we merged with the FD.
Because we became the 11th company of the FD, we were somehow considered
fire appratus Our new rig, which is lettered "Town of Vernon Fire
Department", passed state inspection with the wig wags installed

I have also heard that the main reason why wig wags were made illegal for
ambulances is due to the traditional head light set up for ambulances vs
the PD's cruisers. For example, most cruisers that I have seen have 2
sets of headlights, therefore one set of lights can stay on while the
other "wig wags". For ambulances, this was not possible as most rigs only
have one set of headlights. In addition, by having a second set of
headlights the cruisers high beams could be used. while the other set is
still in wig wag mode. When wig wags were first introduced, (from what I
have been told) a high - beam overide was not available. Our wig - wags
have an overide that automatically kills the wig wag feature when the high
beams are activated. As I said I do not know how the CT state law is and
I am not 100% sure that our consolidation with the FD made a difference
but so far we have been able to use them without a problem.

Lets be careful out there

This is not entirely true. If the wigwags are set on the low beams, and the
cruiser is using them at night then what does he have to drive with? High
beams. Now I dont know if you have seen the highbeams on a caprice or crown
vicci lately, but they are BRIGHT!!!!!

Hell the low beams are bright as it is :)

Not too safe.

You will see that most cruisers have their wigwags on the high beams as the
intermittent and they do not get up to full power when switched between bulbs -
it is not as blinding to other drivers on the road, but are still plenty
bright.

I've seen times when the wigwags used at night covered the colored lights,
eliminatining a l l possibility of color recognition.

I was 'around' when wigwags made their debut. The original circuit called
for an override so the highbeams could be used as intended at night, but
when the driver went to lows, the wigwags took off. As already noted, the
changing light source is confusing, a point the originators of the
concept also made.
