This seems to be the affects of a bad dinamo charging your battery . If you take a appart the dinamo you should fine a part called in mechanic terms "the bones" they look like 2 black magnets with a wire coming out of them . They are not expencive and you should not change your dinamo untill you try this first a car dinamo is very expencive .

Tips for a great answer:
The interior lamp switch is in the ON position.
The keyless entry transmitter unlocks the doors (illuminated entry).
When the key is removed from the ignition switch with all of the doors closed, the courtesy lights light for approximately 25 seconds before fading out.
Battery positive voltage (B+) is applied at all times through the IP fuse block CTSY LP/PWR MIR fuse 6A via CKT 640 (ORN) through the body control module (MALL) to the courtesy lights via CKT 1732 (ORN). The MALL provides a ground through CKT 156 (WHT) for the courtesy lights under the following conditions:
The MALL receives an input from a door being opened.
The MALL receives an input from the interior lamp being turned ON.
The MALL receives an input from the doors being unlocked using the keyless entry transmitter.
The courtesy lamps then light.
When the courtesy lights are activated by opening and closing a door, the courtesy lights will remain on for approximately 25 seconds before fading out after all of the doors are closed. If the ignition switch is turned to START or RUN within the 25 seconds, the lights immediately begin to fade out. If a door is left open, the MALL removes battery positive voltage (B+) to the courtesy lights after 10 minutes. When the courtesy lights are activated by the interior lamp switch, the lights remain on as long as the interior lamp switch is in the ON position. When the courtesy lights are activated by unlocking the doors using the keyless entry transmitter, the lights remain on for approximately 40 seconds. If the doors are locked using the keyless entry transmitter within the 40 seconds, the lights immediately begin to fade out.
Body Control Module (MALL) Diagnostic Mode
For a detailed explanation of the MALL module diagnostic mode, refer to Body Control Module Cell 51.
