Find yourself a set of LEDs. Most that I have seen have a vary wide voltage input range. And they draw next to nothing for amps.
I just installed these on my HJ61. They draw 3.2 amps each at 12V and 1.7amps on 24V. They are a 7" LED with three pods. Two are spot and one is flood. LOVE them. There are varying qualities of LEDs out there. I have cheapos and expensive and in between. In general you get what you pay for. I like the better/more light of the better pods but I am not willing to pay the $$$ for them. BUT there IS a difference. I bought three 20" LED that ranged from $50, $100, and $400. The $100 light gets my vote although the $400 had considerable more light. The light on the $50 light was OK but it had radio interference and you could tell it was a cheaper build just by handling it although it looked identical to the $100 light.
Awesome info! How did you wire them up? Like I said I would like to just splice them into the factory wiring so I can just use the switch that's already there and keep it more original. Trying to keep it simple haha.
I asked the question on here before about this switch on my dash (furthest left) and I was told that is in fact a fog light switch and that the two connectors on the side of the battery should be the wire harness for the lights. The lights were not on the HJ when I bought it. So I'll have to experiment to find out for sure.
