Cool cheap mod for the interior lights...
Change your interior dome lights (2 or 4) and door lights (2 or 4) depending on Tundra model with colored "mood" lights Part # 194B. Comes in many colors, i put blue in my crew max. You can also replace the driver side under dash light with a colored LED light to match the rest. It gives the interior a nice blue colored tint that looks cool at night. Some people may not like it cuz the lights are dimmer and tinted. But i think its different and looks good.
