your lights are likely operating on 13.5-14 volts powered from your converter or alternator, thus the need for a resistor.
i installed a led fluorescent light replacement kit # jc-42-fl from jirah over 2 years ago. i run it about 18 hours a day. it does not state that it has a resistor, but it has a bridge rectifier to correct for polarity.
in response to your post, i just now inspected the light for heat damage. there is no evidence of heat or damage. it is running cool. my kit is ''designed for 12v systems'' which imho normally operate on higher voltage than 12v.
my led is 6400k cool white. i would rather it be warm white, 4500k.
jirah led lamp kits are rather expensive but in my experience they work well.
the package does not state where my kit was manufactured.
