    Early Aerodynic?

    Here is mine which has plastic bulb holders but a "full" grill. The overlap on parts is interesting. Also taking into consideration repairs is important, people used to actually move lightbars from old cars to new. https://elightbars.org/forums/threads/aerodynic-24eah-a1f.94405/

    Whelen ROTA-BEAM Family History

    There is an airmail site complete with the giant ground arrow near-ish to me. The LEDs in the prototype I posted are a great example of different applications requiring different methods. Just because it appears to be rotating doesn't mean it casts the beams as required.

    Whelen ROTA-BEAM Family History

    I never saw a video, but I understood that it looked like it was rotating, but didn't serve its purpose. Apparently rotating beacons at airports are supposed to throw visible beams out, not just look like rotation when viewed directly.

    Whelen ROTA-BEAM Family History

    I always wondered if Whelen made a rotating ground/tower light. They made a prototype in LED when the rotabeam LED came out (need to find those pics). Cool info. Airport "rotating" ground light led tech

    Carson dual tone siren

    Have you played with the dip switches that select how tone two behaves? We had one of these on an ambulance I ran on when it first came out and I must have gone back and forth on the setup daily. http://carson-mfg.com/wp-content/uploads/SA-441-10_Manual.pdf

    9308NLED

    Not a problem. I find it funny that Whelen forgets they made this bar in the space between the edge and the freedom. DC FD still has a few in service. Also of note is that there were micro edges with the 45 degree 5mm heads for longer; a few years before and after this bar. Enjoy the bar.

    Warn Industries 1978 24v Strobe

    That's what I figured, everything seems to be present except the voltage needed to flash. The wrong bulb being installed was kind of a red herring. I'm going to play with that some more tomorrow. I was successful at reforming capacitors on other strobes, I will keep at it and replace it if there...

    Warn Industries 1978 24v Strobe

    With the incorrect Whelen bulb inserted it was just hissing. With the wrong bulb removed I hear the tick. With the bulb pictured below installed I can hear the tick AND and an attempted charge up each time. I'm not getting high voltage at the capacitor. I assume the capacitor is bad, I'm getting...

    Warn Industries 1978 24v Strobe

    I guess either way I need to make sure I find the right bulb to keep testing. Between the bulb drawer and other beacons I'm sure I have sonmething.

    Warn Industries 1978 24v Strobe

    It took me a while to test it, but it just hisses. I need to make sure I don't have the wrong bulb in it. It was sold as not working "thought it was just a bulb but it wasn't" which leads me to think they swapped the bulb with the wrong one. I will need to see what I have lying around.

    Green LED Rotabeam 600

    That's funny. I rarely get presents I actually would have bought myself.

    Any truth to this power supply statement?

    The rotators are definitely a lot more on speed than standard 12 volt gear driven ones. The 120 volt direct drive motors are significantly nicer quality from what I can tell. I also believe that there is a more specific flash rate requirement for certain industrial signals, which is why the...

    Any truth to this power supply statement?

    That's interesting, I think it's also worth noting that the strobes that were being referred to have DC power supplies and AC inverters in them. I would be curious if actual AC power supplies do in fact stay more synchronous.

    Any truth to this power supply statement?

    The strobes I thought. They aren't synched, but appear less "out of synch" than some other multiple flash style lights. I believe the closeness in flashing is being attributed incorrectly to 120 volts AC. Even though it's not really synchronized, I believe the slower flash rate makes it appear...

    Fed Signal SSP3000 Series A amp not powering on when connected to 12v DC power.

    I am not sure if they kept it up, but at one point the cables looked like cat but the order changed between the two ends. I assume that is just a way to sell you $50 cable or someone designed the two boards differently and cable order is cheaper than moving contacts on a board. I know someone...

    Any truth to this power supply statement?

    I got a comment on my youtube 120vac video. Any truth to the Reply or My Reply? Comment-Interesting how the 120v lights seem to "keep time" better than their 12v counter parts. Reply-This is because the nature of AC voltage acts like a built-in clock signal, so the lights are synchronized by...

    The cat 5 cables federal used twisted from end to end in some applications; ie the start and end positions were reversed because "reasons"

    9308NLED

    Never mind, I found the wiring guide. Despite what Whelen says, they made it. Here is a PDF and some pics from it, looks like each pair had their own ground and power. Regardless, this is the stock configuration for wiring.

    9308NLED

    Whelen often forgets that they made some hybrid LED bars with 5mm leds while the Freedom was in the works. I can tell you how to hook it up if I can see the harness. The strobe version wiring is a bit different. The 700 5mm LEDs, unlike the early linear LEDs in the Freedom and Patriot, did not...

    First, here is some info on one that a member had. https://elightbars.org/forums/threads/latest-grab-whelen-9308nled-lightbar.61597/ Here is some 2001/2002 catalog info These bars were pre-freedom and used 5mm 700 series LEDs in a firemaster edge frame. They often had a halogen piercealert...

    Code 3 NightProbe Bar

    No it is not listed on that list, you are correct. If you look through for "3" under the contacts/connections section you get a lot of equivalents, all listed as headlamps for various small vehicles. When you google them they all have very fluted lenses, the 3 contact exception is 4700 which is...

    Code 3 NightProbe Bar

    I ordered a 4454 bulb and got a 4440 some years ago. it a wattage difference. The fluting is the same. Here is what I found. 4440 4454 The fluting stays the same-ish, they are listed as atv/motorcycle/scooter headlamps

    Austin Electronics, Flyers and Mini Catalogs 1990s

    I have rescanned all of these I just don't have the space here to upload them. In fact I have scanned tens of thousands of pages of Whelen and Austin catalogs and literature now, I just need to get the site itself downsized and the storage to post the archive upsized. Do you have a specific...
