Brake Bar Lights on top of Hatchback on 2001 GMC Yukon XL 1500

The bulbs are all out on it, can I replace just the bulbs? If so How do I get it open. I have taken it off truck.

it should be an led strip. which in those you have to replace the whole unit, seeing as how theres no way to replace just the bulbs on the in assembly itself
Really? Auto parts store sold me bulbs !!! Told them it wasnt bulbs but that's what their computer said!! Shouldn"t I be able to open it to get led strip out?? Can't figure that out!!
