Thank you so much for the answer. Of course I'm in no rush, just wanted to do a suggestion.
 
By the by, I forgot to mention "file name" when I was saying ELS Compatibility. I was confused there for a moment, apologies for the confusion. What I meant by there is some authors don't include the ELS compatibility in the file name, they only do so inside the mod page where the "File Information" section located.
So what I was thinking is, of course I don't know much about coding but it was just a thought, if it would be possible to include File Information section to search filters maybe, then we would be able to choose ELS or Non-ELS filters.
 
But of course I don't know much about coding unfotunately but I'm in no rush either :)

To be frank with you, the search function is something that we haven't liked for a while. Right now there are few things that make it useless for a community our size, including the fact that you cannot tell it to not include comments/reviews and our custom filters are very hard to integrate in to the search due to the difference between how the search and our category pages work architecturally.
This is something that we're very eager to improve, but it's likely we will have to throw the search code from our forum software vendor away completely and do something from scratch. Basically, this is more on our long term roadmap than our short term one to the effort involved.
But we hear you loud and clear -- the search completely sucks. We have tried to do our best to improve the category pages, and we will add a small keyword search there in the short term, so you'll be able to filter based on stuff like ELS/Non-ELS, as well as by keywords. We hope to have something on this soon.

You can also use Ctrl+F3 to search for the file you want in OpenIV as well :)

How do I find the current hashes for the Sirens and their car or is there any list available? Since the one from 2016 in this forum doesn't seem to work for me anymore

For the intensity
I believe you'd have to find the cars headlights in the carcols.ymt and change it there, however that would change the value for the car's headlights as a whole For the flash pattern
Look at the attached picture. At the top of the carcols entry for the vehicle in question, you'll see these sequencer values. For mine, in this pic, they're all at 0 meaning the headlights won't flash at all with the sirens. Simply create a 32 bit integer (i.e. "10101010101010101010101010101010") and convert it to decimal form and replace that number. This site will do it and even gives you a neat visualization of the flashing (everywhere there's a one) http://www.binaryconvert.com/result_signed_int.html?hexadecimal=AAAAAAAA
