Interior lighting problem

[hardrock121]

A new problem with my 07 tundra. When I turn on the headlights, the lights for the radio, computer, A/C Controls, etc go completely out. I've adjusted the dimmer swithch with no result. Backlights on everything seem to work fine until the headlights are activated. I've checked all fuses under the hood and in the drivers kickpanel and have not found a problem. Are there any additional fuses anywhere I should be aware of or can someone suggest where to check next?

Tks

Check the dealer next, have them look at it. There isn't much to check and it sounds like you've checked them already. If the lights do work, but not in a different situation, it sounds like a bad relay not switching or something.
