How To Change & Customize Tail Lights 1985 MERCEDES 500SEC 560SEC 380SEC

The Mercedes 500SEC features the iconic "ribbed" taillight design. It uses deep horizontal grooves across the lens. These ribs keep the lights visible in snow or mud. The tail light bulb is typically a standard 1157 dual-filament bulb. It creates a smooth, aerodynamic blend with the car's body. Why the Ribbed Design WorksSafety: The ridges allow light to shine through even if snow, ice, or dirt covers part of the light. Self-Cleaning: The grooves stop dirt from building up over the whole lens. Maintenance and UpgradesReplacing Bulbs: You can replace the stock 12V bulbs using the AutohausAZ 500SEC Catalog to find the correct parts. LED Conversions: Some owners swap the stock incandescent bulbs for LED plug-and-play sets. Be sure to use CAN-bus compatible bulbs. This tells the car's computer the lights are working. It prevents error warnings on the dashboard.
