The ones you linked are Alpha Rex in your original post. Notice how there is virtually no useful information in that link? Its because there is nothing worthwhile spending that money on.

 

I bought a pair of used alpharex lights and ran them for a day before swapping back to my stock halogens and buying the Morimoto XB Hybrids. Just spend the money once and get the Morimoto lights. I also upgraded to the matching fogs.

 

^^^ That is a good looking truck sir
