So I have always thought it was stupid that GM decided NOT to install an underhood light from the factory. It's a $50k+ truck for crying out loud.... maybe that's why they didn't think it needed it... anyone that can afford it probably would just have it towed to the dealership... lol
Anyway it has always bugged me because " I do my own stunts " so I took some left over LEDs I had laying around and an old "mercury/hood switch" and wired them up today.

I cleaned the hood with alcohol where I intended to stick them and then stuck them in place. I was worried the tape wouldn't hold up to the heat under the hood so I drilled 1/8" holes on either side of the strip about every 6 to 8 inches and ran a zip tie through and around the strip to secure them for the long haul... hopefully.

I wired the strip to the mercury switch and tucked everything inside the hood bracing out of sight. I drilled another hole to run a zip tie through and around the mercury switch to hold it tight to the inside of the hood brace.
I then attached the positive lead to the wiper fuse and grounded it to a bolt on the AUX battery tray. I put some wire loom around the wires where it exits the hood brace at the lower driver side of the hood.

It seems to get the job done pretty well.

Pay no attention to how dirty the engine bay is... I need to clean it up some time.
Hopefully this works out well over time and the heat doesn't affect the LEDs negatively.
