I use ELS, but I want to try doing a few Non-ELS vehicles. I am just wondering if there is any way to break the limit of Non-ELS lights. I think there is a certain limit on different vehicles.

I believe the limit is 8 and I also believe there is no way, without using extras, you can get more. I may be wrong, however.

I'm pretty sure one of he vehicles has a limit of 10, FBI slot has 4 and the rest are 8 however I could be wrong.

Scripts like EVCS allow you to add more non-ELS lights to your cars; however, there is no currently known method to break the limit internally.
