Power lights on 2nd trailer from 1st trailer lights. No need to run wiring all the way to the TV.
If you can easily access the wiring at the tail of the 1st trailer, tap them (waterproof it) as far back as you can. 2nd choice would be to pull wiring to tongue of 1st trailer and access wiring at junction box. Each trailer will be different, so you're on your own.
This sounds like the best ways, the only other thing I would think about doing is to change the tail/brake lights out to LED,s on both trailers to minimize electoral draw on tow vehicle and first trailer's wiring.
