I'm currently on a modding hiatus, so there won't be any news in the near and possibly even the far future. I was planning to update the marked CVPI to support 32 sirens (requiring SirenSetting Limit Adjuster) and use the additional sirens to add (optional) mirror lights and lights on the rear deck. This has been on hold due to my hiatus, though all the existing lights have already been converted to separate sirens for SSLA and the new pattern showcased in the video above.
This 32 siren version of the marked CVPI is in a state that's likely ready for release, but won't be officially released until the additional lights have been added. However, as I have no idea when I find the time and motivation to get back to it, I've decided to release it as a prerelease version. It has the updated patterns and uses more than 20 sirens, therefore requiring SSLA for all lights to work properly, and it is otherwise identical to the last released version.
