OpenStreetMap
I have a seperate highway with two plus two lanes (total four lanes). I want to map a u-turn which is a third lane with a stoplight (at the stoplight there are five lanes in total).
Does anyone have any suggestions? A link to a wiki which describes this or a link to an actual map location doing something similar would be very helpful.

There is a proposal being discussed about turnlanes: osm.wiki/Proposed_features/Turn_Lanes
If a way's direction is toward stoplight, then tags would be:
lanes=5
lanes:forward=3
lanes:turnback:forward=1
Also, you'll need highway=traffic_lights on the node where the stoplight is. There is currently no way to map stoplight for each lane separately.
