Understanding the Stock Headlights

The stock headlights on the 4th gen Prelude (1992-1996) are more than just functional components; they're an integral part of the car's iconic design. Let's break down the details to give you a solid understanding.

Design and Functionality

The fourth-generation Honda Prelude featured a sleek, sporty design, and the headlights played a significant role in achieving this aesthetic. The stock headlights are rectangular, with a dual-bulb setup – one for low beams and another for high beams. This setup provides adequate illumination for most driving conditions.
