AlphaRex Is a relatively new brand in the automotive aftermarket industry. They've become known for building headlights that are unique in style, offer various color choices, and better than average construction quality. While (in our testing) they don't do as well as the slightly more expensive Morimoto XB LED headlights, they do offer good bang for the buck and certainly worth considering.

AlphaRex Design AlphaRex developed the Dodge Ram PRO-series headlights based on its stock design and add a LED tube around the edge as DRL and sequential turn signal. At the side of these Toyota 4Runner headlights is the amber reflector lens, and there are amber halogen light bulbs at the side for turn signal light as well. These projector headlights are with dual projector design, with the outer projector as low beam, and inner projector as high beam. The headlights use basic H7 halogen bulbs for low beam and another H7 halogen bulb for high beam. You can also upgrade them with a set of high output LED bulbs for even more light on the road. LED Projector Technology AlphaRex integrated their patented rectangular projector lenses into the Dodge Ram Pro-series headlights. The projection cut-off line is perfect for American LHD regulation. Feature: The Alpharex Dodge Ram Pro-series projector headlights come with sequential turn signal light as well as DRL light tube. Housing: The Dodge Ram Pro-series projector headlights are offered with either a chrome, matte black, or shiny midnight black housing. The chrome housing gives your truck a stock housing look and match your truck if you have a lot of chrome accessories.
