[06 SierraCC]

I have an 2006 sierra,and swapped the lights easy.

But i bought oem lights from the dealer pricy but i felt in the end it would be the simplest.

They came with everything i needed swicthed in the parking lot before i left.

Hope that helps

I bought a set of used OEM Denali headlights off of Ebay for my 2003 Sierra. They are almost a direct replacement for the stock headlights. They will bolt right in, but you will need another set of 9005 bulbs, because the Denali's use four 9005's instead of 2 9005's and 2 9006's.
