That is hilarious. The specs clearly show the LED is 12VDC, but the contacts are rated @125VAC. I did a quick google search for similar switches and the problem seems endemic -- they are all rated at 125 or 250VAC with 12 or 24VDC LEDs! The Chinese at their finest...
Anyway, sorry, I misunderstood about the switch failure question. So, if you use 1 switch per light bar or use a relay, then you should be within the capabilities of that switch.
If you power both lightbars through that switch, then I think you would approach or exceed the capabilities of that switch. In that case, I think the most likely failure mode would be that the contacts would arc each time the switch was operated. The arcing would eventually, over a long period of time, "burn" the contacts and they would become more resistive. Either they would stop conducting enough current to activate the light bars, or the switch would get warm.
I do not think the switch would get warm enough to ignite anything. It is more likely that the switch might get warm enough to soften the plastic housing and the switch would stop making contact at all. It is remotely possible that the resulting loose contact(s) could ground out, but a fuse in the supply line would forestall any excessive current long before a fire started.
That said, the above is just my gut feeling. To be absolutely safe get a heavier switch OR use 2 switches OR use a relay.
But that's just my 2¢.
