aftermarket headlight assembly install help?

hey, i bought some aftermarket headlight assemblies, and i took to front bumper off, and removed the stock, but when i began to fit them, they fitr perfect, but the wiring is to short, do i need to splice the wires, or did i get ripped off? please help....

If you want some articles about replacing a Car Headlight Assembly (http://usautolighting.com/articles/), that is the place to go :P
