Out of frustration and just to teach myself something new, I dove into the turbo-flashing strobe problem right after FSX came out. The goal was to learn how to slow down the effect.
I was using the Shockwave B-29 and it's turbo lights as the teaching tool. What I did learn was that it was a fairly consistant percentage of overspeed with each of the lights. Once I created the slowed down files for the B-29, I used those same files on the early Carenados also.
Here's a link to the old post where I posted the "How-To" change the flash rate on the effects files to match the old FS9 rate:

The directions are part way down on the first page.
Overall the "ported" flashers were running not quite 3X the normal rate. The factor I ended up dividing the emitters by was around 2.9.
To keep the asynchronously flashing lower recognition lights I just kept the new rates for those three lights slightly different, 1.07, 1.06, & 1.00. That little bit of difference made them look like the were flashing on a completely random sequencing.
Here are those same old converted and edited original WOP Recognition Lights mounted on the new Accu-simed B-17.
