    So I have a 2015 TRD off road and I believe mine use H11 headlights. I have read through the ultimate light upgrade as well as many of his other posts and I am confused. Can I use H4s in my truck and if so do I need to do the ultimate upgrade I order to have H4? Do the TRD pro lights use H4? I am looking to upgrade my lights and I want to do it right I am just a bit confused on the difference in bulbs. And are the 2015 TRD Pro headlight assemblies a direct swap for mine? Thanks guys I know it’s a lot

    TRD Offroad uses 9003 (H4) in the headlight and H11 in the foglight, not sure about the TRD Pro headlights.
