Here's a cheap gift to give someone for Christmas. LED lights for car interior are great. They are cheap (About a dollar), brighter, use less power, less heat, and are whiter. I bought some from Amazon where I got a 10 pack for $7. Very easy to replace. Just pop out the plastic and pop in the new bulb. The above picture shows the one on the left is the LED and the right is original.
LEDs are polarized so if you put it in backward it won't light. Just turn it around. You need to match the bulb size which you can do by looking up your car online. Generally just match the length like 31 MM or 42 MM.
