Pros: Bright as hell, cheap.
Cons: Need multiple inverters depending upon your location of the cathodes. Do NOT, I repeat, do NOT extend the cahode wires. ONLY extend inverter wires.
Comments: Holy hell, there was actually a LISTING FOR THIS?! Now I don't feel as ingenious as I thought I was. Bah humbug.
But seriously people. If you want dome lights, and only have a roll-bar.. Consider these. They work great, they're bright as hell, and they last for a long time. Plus, you only need a 2Amp fuse.
Just don't drown your jeep.
