It will depend on some things. Do you have a top? I bought a 40-inch light bar, but the plastic roof wouldn't support the weight. I could have our some holes in the roof and mounted the light bar directly to the roll cage, but then I started running into clearance issues with my windshield!
I mounted 2 pods (6 LEDs, each) and they are more than adequate... Especially considering the 25 mph top speed.
