Auxbeam F-T1 H11 (70w/8000lm)
Comes with a ballast but you don't need it. Which is nice cause you don't have to cut holes in dust caps. They work great and are about $50 on Amazon. TRD Jon on YouTube did a review on them you can search for it.
You can see in one of Swell Runner's YouTube vids what the bolts look like under the roof (his is a front runner but same process). You can see how he screwed up and fixed his if you watch whole thing. He a pretty down to earth guy.
