They did offer conversion kits, but I don't remember one for a 6volt light (what it's attached to in your pic).
A local gun show that I set up at.So, where did you "pick" them up ?
lol the bulb in that throw head cost more then $20!
What do they fit? Certainly not a 6P. Way too tall.The Ultrafire P60 modules are cheap Chinese but are usually good enough for the money.
