yes they are inter-changeable. i did it on my friends crew cab titan. switched out the doors for the doors, the license plate lights for the license plate lights, and so on..... BUT if you had the more basic titan(or older), you dont have lights in the doors and can only change out the dome light in the middle for the dome light in the coupe, NOT the front reading lights. hope this helpedjuztplayin12 wrote:thanks, im looking at interior led bulbs to do first. then windows. then possibly spoiler and lowering. anyone know if the interior leds will transfer from my new titan ti this car?
