There are at least three different optic patterns: horizontal, vetical, and checkerboard.

If not, I'd like to be second in line after @motionman427!

The pattern selection is supposed to be the same as on the UHF2150B: Source: https://www.whelen.com/wp-content/uploads/2020/08/13531.pdf In fact, I had an older copy of 13510.pdf from February 16, 2000, which I have uploaded, here: UHF2150A-Headlight-GrilleLightFlasher_install.pdf

Those are Whelen pylon mounts.

Please don't hesitate to ask for help if you need something!

I remember a thread with photos of something very similar to what you're describing many years back, but I have been unable to find them again.

I sincerely wish we could have worked to sort through the broken links while the images were still available.

It will take quite a bit more power to engage the relay than it will to keep the relay engaged. You can expect a higher current requirement for a small fraction of a second when engaging the relay. However, in practice, this is negligible in the grand scheme of things. The coil of a common...

You could also use the dry contact relay to switch something that does not connect to either power or ground, such as the audio output from a radio or scanner.

I'm happy to have helped!

I concur. It appears to have nine diodes and three open positions per side.

Yes, 24awg is far too small. At minimum, match the gauge of your extension wire to the gauge of the flying leads coming out of your speaker. Going even larger is okay. Get rid of the 3.5mm plug and jack.

A 537 is pretty small once you take it out of its can. Doing so can be quite tempting when a small space is all you have to work with. However, removing the can alters the thermal characteristics of the flasher and could lead to an even more lopsided flash.

I much prefer the Mickey Mouse style over the pair of meteors.

Wattco has a list of modifier guides, one of which may be of some help: https://www.fcausfleet.com/content/dam/fca-fleet/na/fleet/en_us/dodge/2017/durango-ssv/docx/Durango_SSV_Upfitter_Guide.pdf
