I was looking at retrofiting a set of spyder headlights, came across this thread on here about someone doing it with a similar looking set of lights. He says they are eBay light, but they look identical to the spyders.

He used an older version of the fx-r projectors, which were commonly used for retrofitting. The newer version of the fx-r is what a lot of people are using in the stock reflector type headlights on the f150s
