I have a 2012 SB Express. I've been having a discussion with a coworker about changing out my headlights for brighter ones. My coworker also has an EXPRESS though its a quadcab. So we both assumed we had dual headlights and for a replacement that's what I bought. I even verified the build sheet code LMAS HALOGEN HEADLAMPS not the LMEP - Halogen Quad Headlamps
. Well it turns out I have QUAD headlights. And my coworker has duals. When we looked at them, we could see an obvious difference. Anybody else with a SB EXPRESS like mine? I figured I'd give a heads up for anybody else planning to swap their headlights .It was no big deal. I hadn't opened the new ones I bought, but I did end up buying high beams too.
