LED's don't get hot, so no.
No reason to ever unplug any lights before you launch except for the ancient ones that weren’t sealed. If your sealed lights have cracks in them, the water that got in during launching will crack the bulbs when you plug them back in anyway. Better to know you have a bulb blown than blow one on the road or take a chance of forgetting to plug the lights back in.
If you have integrity, nothing else matters. If you don't have integrity,
nothing else matters.
If the assembly is rated waterproof it's OK. Some LED's are, some aren't. Even if they say waterproof sometimes they fail.
