What type of light bulb is used in the analog clock dash a 2001 Chrysler 300M?

The analog clock in a 2001 Chrysler 300M uses a standard miniature wedge base bulb, often referred to as a wedge bulb or sometimes a festoon bulb. The specific size might be a 1.2W or similar low-wattage bulb; you'll need to carefully check the bulb itself or a parts diagram for the exact size/part number before replacing it. Auto parts stores can help identify the correct replacement.
