Ultrahead Upgrade Kit

[JAS]

What is the difference between Ultrahead Upgrade Kit 78003 and 78004? Does one of them have an adjustable focus? Which one?

78003 converts a Superstinger (discontinued model) to an Ultrastinger.
78004 converts a Stinger or StingerXT to a Stinger HP.

Reflectors are the same, bulbs are different. All Stingers have adjustable focus.
