It seems like you're referring to a Wiper Blade 12A, but there might be some confusion or missing context. Let me clarify a few possibilities:

1. Wiper Blade 12A: Typically, this could refer to a specific model of windshield wiper blades, likely made by a particular brand like Di or something similar. Wiper blades come in different sizes (in inches), and 12A could denote a 12-inch wiper blade that is designed for a specific vehicle model or make.

2. Brand or Model: You might be referring to the Di brand, which is a common brand for automotive parts like wiper blades. It's essential to know if you’re asking about a specific brand or product line.

3. Type or Compatibility: If you are looking for a wiper blade for your vehicle, the number 12A might refer to the model, and you'd need to verify its compatibility with your car's wiper arm.
