Whelen Core - West Union PD

Zack gives us a detailed look at a Core system from Whelen that we have installed on a number of our builds including this one from the West Union Police Department
Karl Chevrolet has been in the same town for more than 40 years. We are located just off Interstate 35 in Ankeny, Iowa.

Great looking build. Also LOVE the editing, quick cuts, right to the point for each feature, very nicely put together.

[@erijriela.bondoc5521]

one of the most best Whelen Core programmed I have ever seen. Kudos to the one who programmed it.

[@cam2ss1le14]

Nice build. I really like the fading in and out pattern, very unique and effective.

[@ryanlong1]

Wow love the DVI pattern! And the gun lock count down!

[@Genezis-88]

Looks like K.I.T.T 😍😁

[@alancotton8404]

Nice to see that when "on seen" the lights don't have to be so blinding to oncoming motorists, erratic lighting systems can sadly cause more accidents than preventing an accident. A nice pulse flash is surprisingly effective.

[@dagwould]

Dead right. The arrays with rapid random flashing arrays are distracting, not informative and take drivers longer to figure out what they should be paying attention to: Is it one vehicle or many, is it moving or not, and where to? etc.

[@Rummeltobi]

Nice showcase and great built! :)

[@stadce]

I like everything about this build except for the cruise having flash. The whole point of using cruise is to NOT have flashing lights, just a steady burn.

[@jeffersonbyron3494]

instablaster...

[@kennoetzli8645]

Awesome work

[@drew9932]

Whoa! the fading in and out.. wow! Never seen that. I do feel its backwards. The Cruize should have a smooth fade without the flicker though

[@Focusonbehind]

DVI looks good. That is something unique.

[@tannerthomas6694]

not how i would’ve programmed it but i respect the thought and time and everything that got put into it!

[@dagwould]

How would you do it, and what research would you base it on?

[@craigclaassen7346]

Wish my service allowed control access to the siren and lights, other than just on/off switch.

[@CadeClark-e8c]

What brand is the whip antenna on top???

[@patrickirwin735]

What pattern is the takedown pattern on the FST?

[@mikeellis4158]

From studies done back in the eighties it was found that yellow and clear light were seen better at dusk/dawn. But I don't remember which way the color went. Could this system be set up so you would have clear with the blue lights and yellow with the red?

[@dagwould]

CHP did a lot of work on warning arrays. I think Ford coordinated some work as well back then. Is this what you are referring to?

[@edgargarcia940]

What's the price for this setup?

You must define the acronym DVI or DBI & SAE? Additionally, based on who’s quantitative testing, we’re they clinical tests, were they mere random hypothesis based on experience from random LEO ( law enforcement officers) , this would be most helpful, particularly before one indulges their agency in 8K-15K of upgrades for each patrol, detectives, staff sedans , SUV’s, pickups , etc. etc. . On a different context, the markings look exceptionally futuristic, and make the vehicle look quite professional & authoritative, and the professional amenities required for LEO entities look like particularly cutting edge & visionary for public safety vehicles. I never like to view long filmings of anything other than educational or those of academia, however since you have quite a propensity & dexterity for the engineering of your corporations up fitting & outfitting , perhaps you might want to increase the the filming since you do state of the art ideas which interface extremely well for LEO’s , as well as public safety vehicles, advertising would also help towards the end of the video. I’m sure colleagues of mine & of others watching your video feel much the same relative to the new & innovative accessories & methodologies of the manner in respect to the shutter of the lights particularly on the grill & deck of the vehicles that you up fit, as it makes perfect sense incorporating white w/the blue grill lights, yet keeping red with its stand alone color of red, this made the front acutely striking, as well as viable. Thank you, so much for your video , God Speed & and God Bless you , aa well as all first responders ,who utilize vehicles like yours ,daily while conducting their daily tour of duty, thus every single amenity could actually mean the public safety of civilians and/or first responders.

I sort of agree. The ideal patterns seem to follow the work of Berkhout (in Human Factors, I think it was published) and Crawford in 1962 in Ergonomics). This resolves to bi-lateral symmetrical phase and color of flash operation for all sources on the vehicle. But the litmus test is driver behavior on the road, validated by crash statistics and response times.

[@dagwould]

Looks good. I'd prefer to see larger lights than the 1x4 LED sets; I think 4x4 LED is the practical minimum for good spatial awareness. Small sources become point sources at any distance and so loose 'depth' plus can be very hard to even see in day time. For good observer tracking, flash arrays should always be bi-laterally symmetrical. This creates a stable baseline for triangulation of distance and faster safe driver reaction.

Federal Signal Rumbler :P

[@FFred-us9tw]

This was not a Rumbler, this is a Howler. Same principle, different brand and system.

[@V1AbortV2]

Red & blue should never flash together 🤦🏻‍♂️

[@Genezis-88]

Why?

[@chpman2013]

What do you mean?

[@dagwould]

Exactly. They imply different perceptual depth: that is they appear to be different distances from the observer. In day time it is worse. On bright days blue fades to nothing at normal driving 'look ahead' distances and the signal ends up as one asymmetrical indication. They also stand at opposite ends of the eye's sensitivity. Red itself is poorly seen when eyes are dark adapted, blue is seen better. Light colors appear to not be sensitive to this: red lights disturb night vision less than blue which tends to want the eyes to adjust to daytime sensitivity. Together, the bi-colour arrangements impede the observer's establishment of a baseline for stable triangulation of distance. Particularly in complex road fields or in multiple emergency vehicle scenes the observing driver is presented with an un-interpretable confusion. The result on the observer from all this is visual confusion. This translates into workload and increases response time and decision-making.
