These bars in stock LED form look great

How can i buy it please give me one for my excavator

Very interesting. Would like to know what aircraft this light came from. Also, on the blue, as stated before, blue lens and an incandescent bulb give the deep green tint required at the right side of the wingtip.

Can we see an outdoor distance video please ?

Great outcome!! The way it should have been!!

Love that!

this looks better than anticipated.

Yeah... that era went away too early

Ultimate!👍

That fixed the problem, nice job!👍

That looks great!

Sex

Would love to see an observation of directly overhead a slightly considerable distance in the dark

Good Work!

I would love to see an outside from a distance video. Amazing work. D-Tech have long been a bucket list item for me.

I want one :)

Do you have any 99 series domes for sale by chance?

Wow 🤩 love this video

Didn’t know D-techs were a factory option. Usually these were aftermarket replacements that didn’t work well as most rotator speeds were too fast to get effective flash from these.

Synced like that and with slow rotation is definitely how they should've been from factory. Whether they flash the same color or alternate having them go slow and in sync definitely improves their effectiveness

To me D-Techs need to be as slow as the old sealed beam rotators to be effective.

Great experiment!!

yeeesss its perfect... the whole thing is a massive improvement over the factory independent rotors, and yes, opposing rotors are always more efficient than sequenced rotors regardless of lens and color

Fun times!!!

Now that actually looks good! Thanks for the videos on the d-tech rotors. Definitely looks better when they are slower and opposed colors.

My two lens XL9000 bar sucked the juice, if this one fit on my SUV it would have imploded!😂 Actually, I ran my bar for years on my Chevy S10 Blazer and never replaced the alternator with one delivering a higher amperage. Was very close to this: two red domes with the driver side having a clear insert. Rear had two inboard amber panels and select alert that allowed for amber only in the rear. Clear end caps for intersections. I always considered modifying it for halogens but really liked the select alert. It was an awesome bar and my department let me do things like respond onto the interstate and cross major multi-lane roads because I had it. Other volunteers who had the crappy two rotator mini-bars were limited in where they could go. My captain had a Federal 12X bar and that one was nice too. Thanks for bringing back great memories of the FD from nearly 40 years ago!

That’s a very nostalgic light bar. LAFD ran them for years in all red no stingers. I always wanted one.

good lord

My favorite lightbar next to the 9600 series and MX-7000's!!

If anybody is interested the patent number is US6585399B2 for the D-tech rotators applied for in 2002 expired in 2019. Overview of the patent: The use of absorptive filters in light bars and warning lights for emergency vehicles is well known. One major disadvantage with such absorptive filters is that they absorb light and thereby reduce the intensity of warning signals being provided to observers. In addition, the absorbed light creates heat in the absorptive filter which can be problematic. There is a continuing need for warning lights which generate brighter signals, varying colored signals and multiple signals because such lights are usually more visible and usually are more effective in alerting observers. In addition, there is a continuing need to reduce power supply requirements. Although absorptive filters with multiple light sources may increase visibility, such a combination requires more power. Therefore, there is a need for warning lights which produce more visible signals without the concomitant increase in power needs.

Since these are stupid expensive, i wanna learn how to make one

they look even better when the pods are properly aligned

Sounds like there working for it

I definitely prefer the slower end. I always wanted to see a DTech in a FireBeam with the UF7 mirror - that would be an incredible dash light.

Wonder if having protruding side ‘blinkers’ may help to not see both colours on the edge plane?

There was a guy the next town over from me who would take these and remove the halogen stuff, plonk some whelen 800 or 1200 split domes on the rotor trays, put the power supplies in the speaker housing, and retrofit the plinth to hold the strobe tubes... it was SUCH a wild thing to see. The beacon lenses would spin around the strobe tube and create dual color strobe warning.. he applied for patents and tried to sell the idea to the OEMs, but by the time it got off the ground, LED tech was the forefront..... i think he put a couple videos on YT but i forget his channel name

22" geared Aero with a resistor or a pot would make a ton of sense... as far as what speed, basically take the usual factory single color RPMs and halve them? interested to see where you go with this...

FIFTEEN LAMPS! Daaaaaang

Reminds me of AT&T Long Lines Towers....Where it was going was good, but became rapidly obsolete

Last week just picked up a 52" with a single stinger! Force four model?

I thought we had a power drop this morning, that's a big one!

Stunning Bar!

She's beautiful. I could watch these videos all day.🤗🤗

She's beautiful

With over 36 years in the fire service, I’m still mesmerized by light bars.

Aka alternator killer

Hi ! :) Just amazing to see it operate like that , and you seem to have a very nice collection behind ahah ! ;P I've got the same Jet Sonic as this one, could you show me how you "by-pass" the multiplex system ? Because i've already done it for mine but i've only got the 'dumbest" functions like : alley's , takedown , and front or/with rear rotator. No flashing or other chain synchronisation fonctions :/ Many thanks for your answer and greetings from France

D Tech rotators were an interesting concept, but their effectiveness was washed out in the sun. I remember seeing an Illinois State Trooper squad on an accident scene, thinking how useless the rotators were. D Tech bars didn't last long around here.

I would love to slow down my d-tech Excalibur
