I would be surprised if more people did not want a 2 wire arrow function. We are consistantly contracting to put on a lightbar and a rear window stick. We use the cn signalmaster, and I like the light, but sometimes it is just to big and bulky for where we need it (and sometimes it is what will push us over on price in winning a vehicle bid). The latitide arrow does not do flash functions, so you cant use it as an arrow and a flashing light, so I never use those.
Then then next issue, what happens when you are upgrading a car? For instance we have done a few vehicles that were going from an soundoff interior light package, to a full marked partrol. We use an integrity lightbar, and put in an SSP for control of it and all the other existing lights. Without 2 wire arrow, I can't make the old rear lightstick function... (allthough like I said, they did give me a program to do it so it will work). Heck, how about a convergence network device that would "mimick" a cn signalmaster, plug into the network, and then output 2 wire arrow and a "flash mode" function. So you would assign the software to control a rear cn signalmaster, put in this network device, and just mount it near the 2 wire arrow. signalmaster button would work the 2 left, right wires, hazard button would turn on flash mode, and you could assign the hazard mode on slide 1,2,3.
Lastly, I really like using the feniex cobra sticks in rear windows. They are bright, they are compact. If federal were to come out with one similar based on the micropulse series, i would absolutely use it but I would sure hope they would control it with 2 wires, and not use the signalmaster outputs on the ssp. But I thought they would have figured that out with the Latitude arrow too....
I would like to see them add more inputs as well. I use all 8, and could really use more. AN expansion output bank that is more than 4 relays would be nice as well, say 10? with each output being able to be paused, flashed, steady on...
Also, as a tip in case you don't know. Put your Wigwags on output 9 or 10. Use one of the amp inputs for park detect (we will call it input 1). in programming, assign input 1 to relay 9, steady on, active LOW, open off. This will work as a park pause so you don't need external relays to shut off the wig wags. If outputs 1-8 were still able to do "Active low" on the series b, you could "pause" any of them. we use output 9 for "clear warn" and output 10 for mirror beams. We get requests to shut off mirror beams either in park, OR when the specified door is opening.
