We don't make specific recommendations, as that is influenced by preference, and intended use case.
Some people want a small, lighter light, others want a high lumen light, which are often bigger/heavier, some want a replaceable battery, while others want a rechargeable battery, etc, etc.
We have many lights listed as compatible on the product pages of the rails. You can also find many people posting on our social media pages, as well as some reviews on youtube of people using various lights with our rail.
For the Proledge versions of the Tactical Application Rail, accessory compatibility is the same as the regular rails.
