2008 Tahoe LS interior lights

[Chappy110]

So, we picked up this Tahoe up a couple of months ago. The problem I'm having is, all of the lights work when its light outside. Cluster, dash, interior overhead, and all of the outside bulbs. As soon as it's dark and the Head lights switch on, I lose cluster, dash and map lights. All of the outside bulbs are working, replaced the headlight switch with both OEM and aftermarket. I've read that if there is one bulb in the Data system, that it would do this, but I can't not figure out what bulb if any is out, or what the issue could be.
