Selecting the correct tail light requires verifying the specific model year and regional variant (e.g., North American vs. T6/T7/T8 International versions), as mounting points and wiring harnesses differ significantly. Buyers should prioritize Plug-and-Play compatibility to avoid complex rewiring. For high-end markets, Full LED assemblies are preferred over halogen due to their superior brightness, faster response time, and longer lifespan (up to 50,000 hours). Ensure the housing is made of UV-resistant Polycarbonate (PC) to prevent yellowing and cracking under extreme weather conditions.
