Tim, they are multi purpose. Tail/brake/turn..... oh, the link wouldn't open for me but I'll try again later this evening.
I had a new set of chrome bullets and kept holding them up and looking looking looking at them. Then while at a truck shop one day I seen these and the price was right.($32 total) I would love to have recessed some bullet lights but thought about it after most of the paint work was done. I was worried about these LED"S "protruding" about an inch but since this is not a "work" truck figured they'd be OK. One of the best parts of this is I only have 3 small 3/16" holes to fill if I ever want to change them.
Thanks for your comments guys. I do appreciate them.... and I do plan to put a 3rd light. I just need to go to the salvage yard or see whats available after market. You know, its got to look "just right"!
