This will set your Tundra apart from most other trucks. I just installed a Recon Hyperlight "Line of Fire" tailgate light bar that functions as running lights, turn signals, emergency flashers and an auxiliary brake light. You can also buy one that has white LED backup lights.
The unit is very well made and much brighter than most of the cheap ones I've seen for $30 or $40 bucks; and they aren't sealed like this one.
Super easy install, only took 10 minutes. Most of that time spent routing the simple 4 wire harness that plugs directly into the mostly unused 4 prong trailer plug next to the normal round trailer plug on the factory hitch.
The wiring is totally hidden and there's no drilling. The unit attaches to your truck via small black plastic plates that are stuck on with 3-M industrial grade double sided adhesive. The light bar itself is then fastened to the plates via screws; so you're not having to drill into your truck.
The bar is mounted in the gap between the bumper and the bottom of the tailgate, so it's basically hidden until it lights up... very cool, and the actual bar is so slim that it doesn't interfere with the operation of the tailgate when you put it down.
One thing you will need to do is notch out a section directly in the center of the mounting strip. I just drilled a .5" hole. You'll need to do this to be able to access the crank slot for the spare tire. You can notch or drill the mounting strip without harming the actual light portion of the bar.
As one more side note, there's a small white silk-screened "RECON" logo on the right hand side of the light bar. I'm a purist, and don't like things like that possibly showing, so I took the corner of a rag and soaked it with a little "Goof Off" solvent and it wiped right off. If you do this, be careful what type of solvent you use as you don't want to eat up the plastic, and make sure you don't get any on the clear tube encasing for the LED's or you may cloud it.
The install looks totally clean and factory. The light bar gives your truck a very custom look, on top of being a great extra safety feature. I actually installed this because Utah has some of the worse drivers I've ever seen. 70% of them can't even manage to hold their own lane, and my wife has been rear-ended in stop-and-go traffic on the freeway, 3 times in the 3 years we've been here.
I thought this would give my $40,000 investment a little extra insurance, as it totally turns heads, which is what you want because it means people see you. I even had a semi driver speed up and blow his air horn at me just so he could ask where I got it.
The picture I took isn't the best in the world. It was raining, and the extra lights you see under the main line of lights is just the reflection off the water on top of the bumper.
This picture is just the running lights; and you can see how bright they are. The brake light gets twice as bright, and when the turn signals are in use, half the bar will flash brighter while the running light level still shows. It flashes with the hazard lights, and even flashes with the rest of the lights if you have the factory installed alarm system.
I bought mine for $66.79 through Amazon.com. Free shipping and no sales tax for Utah. (Recon model 26411 60" Red Hyperlite "Line of Fire" LED Tailgate Light Bar).
