Towing a trailer or just want better visibility in your 2003-2007 Chevy Silverado, GMC Sierra, Tahoe, Suburban, Yukon, or Avalanche (Note: for 2007, it's the 'Classic' body style only)? These chrome tow mirror replacements are a major upgrade. They're much larger than stock mirrors and extend outward manually to give you a clear view past a wide trailer. They're loaded with features: power adjustment for the main glass (so you can angle them from inside the cab), heated glass to defrost in winter, built-in LED arrow turn signals for safety, puddle lamps to light the ground when you unlock the doors, and auxiliary marker lights. They also have a handy convex spotter glass on the bottom corner to eliminate blind spots. They are manual folding (you push them in by hand) and manual telescoping (you pull them out by hand). Important: These will only plug and play correctly if your truck originally came with these same features (power, heat, signals). If not, you might need some extra wiring. They come as a pair (left and right) with any needed installation tools. A great way to add functionality and a rugged look to your truck.
