1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical contact while working on the lamp assembly.
2. Remove the Old Lamp: Locate the front right indicator housing. Unscrew or release the mounting clip, then gently pull out the existing lamp.
3. Prepare the New TYC Lamp: Verify that the new lamp’s connector matches the socket type (typically a standard automotive plug). If necessary, trim any excess insulation to ensure a snug fit.
4. Install the New Lamp: Insert the TYC Turn Signal into the housing until it clicks or locks in place. Reattach any mounting clips or screws.
5. Reconnect Power: Reconnect the battery and test the indicator by activating the turn signal lever. The lamp should illuminate brightly and blink at the correct rate.

The TYC Turn Signal delivers a luminous intensity that matches the original Mercedes-Benz specification, typically around 2000–2500 lumens for white LEDs. Its spectral output is centered near 650 nm, providing clear visibility in daylight and low‑light conditions. The lamp’s thermal management design ensures stable operation even at high ambient temperatures.

All TYC Turn Signals undergo rigorous testing, including:

• Electrical Load Testing: Ensures consistent current draw and voltage compliance with OEM requirements.
• Environmental Stress Testing: Exposes the lamp to temperature cycling, humidity, and vibration to simulate real‑world driving conditions.
• Optical Verification: Confirms brightness, color temperature, and beam pattern meet or exceed original equipment standards.

This comprehensive testing guarantees that each unit performs reliably throughout its service life.

• Inspect the lamp regularly for signs of discoloration or dimming. Replace promptly to maintain safety and visibility.
• Avoid touching the glass surface with bare hands; oils from skin can degrade the lens over time.
• If the vehicle’s electrical system shows irregularities, have a qualified technician check for wiring issues that could affect lamp performance.
