VDO Light Diffuser f/Type C & E Wedge Bulb - Red - 4 Pack

The VDO Light Diffuser for Type C & E Wedge Bulb in red is a 4-pack replacement set designed for marine navigation and instrument lighting systems. Reliable lighting, especially red navigation lights, is essential for safe operation during twilight and nighttime, making these diffusers a crucial accessory for any angler or boater.

These diffusers filter and soften the harsh glow of wedge-base bulbs, ensuring compliance with navigation conventions while protecting your eyes during long periods on the water. Engineered as optical components, they mount directly over Type C and Type E wedge bulbs to evenly distribute light and maintain the necessary red wavelength for marine use. Their molded construction provides durability against salt spray, moisture, and UV exposure, which are critical factors in both saltwater and freshwater environments.

Ideal for anglers and boaters with multiple fixture arrays, this 4-pack is perfect for cabin lights, instrument panels, and running light clusters. Whether upgrading aging lighting systems or stocking spares for extended offshore trips, having backup diffusers ensures minimal downtime and enhances safety during nighttime navigation.
