Any of the led haws currently available will fit the 07-11 tahoe tails. I personally have installed the nova 600's, whelen vertex, whelen LAWs, and ArkLaMissLights LEDHAWs in the tahoe tails since the 07 body style change without and issue. All of them are very bright and any of them would work for you. The ArkLaMissLights.com one are the least expensive, followed by the whelen vertex, them the nova 600's, then finally the most expensive (but also pretty much the brightest) are the whelen LAW kits.
If your tahoe is in fact the police package with the loom of control wires under the center dash, then your truck has a built in taillight flasher. To enable it's function, you will need to run a single wire from the drivers side under hood area by the firewall (there is a four pin police accessory plug located behind the fuse box and next to the brake booster and you can use one of the four wires to connect to) and extend it to the passenger side area directly below the passenger side headlamp. Remove the two 7mm bolts and two push on plastic rivets holding the wheel well liner behind the pass side headlamp and reach up and pull on the loomed up connector that is tied up there. There will be a six position plug with a red/white, black, blue/yellow, green/white, and green/black, and green/red striped wires in it. Cut the blue/yellow off the connector and tie it to the wire you ran over there.
Now inside the truck, there will be a bundle of wire under the dash that has white labels that say 6J1, 6J3, and 6J7. Look for the cable that has five wires going to a small gray plastic plug that has nothing plugged into the open end. It will have a green/red, light tan, light gray, blue, and light green wire. The last four wires I just mentioned were what go to the plug behind the fuse box in the engine bay, so figure out which color wire you hooked up to and tie into it. Now install a relay hooked up in the following manner:
87 - wire from the under dash connector mentioned above.
86 - 12v + switched output from your switch box to activate the taillight flasher.
85 - chassis ground
30 - chassis ground
Jotto desk makes the Lazy L console that has 18" of faceplate space which could hold approximate six items. Plus it comes with a long 28" long floor plate and tahoe specific seat bolt brackets, and you can get a cup holder and arm rest that will bolt to the plate, which will maximize the free space in your console for wiring and equipment mounting. Havis also makes a great console for the tahoe. I've installed both, but I personally like the jotto better.
Jotto and havis both have switch panels that include 3-6 heavy duty carling type rocker switches and even some have an extra cig outlet or more in the face plate.
Good luck!
