The quality of this kit is very good. I installed 4 headlights on a 2021 TRD Pro. This is easy to do but the two outer lights require a shave, sanding or a dremel to remove the top lip at lens level for the 2021 model (see image). All the lights just come on. This kit is described as "The lighting kit includes a fused wiring harness for a seamless installation." This is incorrect. "Wiring harness with fuse" is NOT included. The kit contains only what is shown in the photo. You will also need a spade or spade to connect the ground wire.
