EQUIVALENT LEDs run cooler than their incandescent counterparts but that's not what we're talking about here. Stock bulb is 21w which puts out ~120 lumens. An equivalent LED would be only 1 or 2 watts, so 10 or 20 times cooler. But here we're talking about putting in a 1750 lumen bulb - 15 times brighter (I agree it's good to be seen, but holy crap!). I didn't see a wattage for that lamp but I think it'll be around 20w - same as the original more or less. LEDs concentrate their heat in a smaller area so they can have heat dissipation problems. If you get LED bulbs for your home they'll often have big finned heatsinks on them to take care of this problem but these little automotive bulbs don't have that so yeah, they're gonna get hot.
I would think a 650 lumen LED would be more than sufficient (5 times brighter than stock) and not give you the heat problems of these eyeball burning 1750 or 2500 lumen bulbs. Putting a 1750 or 2500 lumen headlight bulb in would be illegal in most states. I'm not sure what the laws are on tail and turn signal brightness.
I ride bicycles a lot and get into a similar discussion about bikes. Yes, you really need to be seen for safety but I don't personally think blinding drivers is the answer (the answer to this I usually get in the bicycle community is "screw those cagers" - I reckon I might get similar comments about SUV drivers here).
