Don't bother with light converters, just park in front of a wall about 10 feet away in the dark, turn on dip headlights and you will see two raised bits of light above what seems to be a straight top line of light. Use some insulation tape on the lens in the place that obstructs that peak of light. Do both lights and you should finish with a light pattern with a straight line to its top, thats it simple.
