Additional Notes

The Mercedes-Benz CL63 AMG uses the 12184 bulb for the back up light across the 2008-2010 model years.
The 12184 is a Philips part number designating a halogen bulb rated at 12 volts and intended for specialty automotive applications.
Halogen bulbs in specialty applications, such as the 12184, are typically designed for precise optical housings where standard replacement types are not interchangeable without fitment verification.
The consistent use of a single bulb specification across all three model years indicates no mid-cycle change was made to the back up light bulb requirement for the CL63 AMG during this period.
Because the 12184 is a Philips-designated part number rather than an industry-standard ANSI or SAE bulb code, substitutions from other manufacturers would require cross-referencing to confirm electrical and physical compatibility.
