Will these work if I install them on my TB? ( SEALIGHT H11 9005 LED Headlight Bulb, High Beam Low Beam LED Bulb Kit,6000K Bright White, Halogen Replacement, Quick Installation )

on Amazon is says my TB isn't compatible but the fit says it is universal.

I have the Sealight H9/H11 for high beams and they work good. I also have Sealight high/low beam LED bulbs in 2 other vehicles and haven't had any problems after 2 years.

Are they easy to install on the TB? my cousin owns a Silverado 21, I changed it to led (same light ^) but it was difficult to install due to tight space and dropped the halogen light, and cannot find where it went lol.

Yes, very easy for headlights. I've had some terrible ones in the past, lol.

Here's some pics of the dust cover on and off with the Sealight high beam LED installed. If you have halogen high & low beams you will have 2 dust covers on each side instead of 1 like mine.
