VDO Light Diffuser f/Type D Peanut Bulb - Green - 4 Pack

The VDO Light Diffuser for Type D Peanut Bulb in green is an essential accessory for any boater or angler who relies on cabin and navigation lighting in low-light conditions. Proper light management onboard isn't just about brightness—it's about preserving night vision and reducing eye strain during extended hours at sea.

These diffusers soften and scatter harsh light from peanut-style bulbs, creating a more comfortable lighting environment below deck while maintaining visibility for chart reading and equipment monitoring. Engineered by VDO, a trusted marine lighting manufacturer, this green-tinted diffuser is specifically designed to work with Type D peanut bulbs—the compact standard found in most marine cabin fixtures and instrument panel lights.

The compact 4-inch profile fits seamlessly into standard marine light housings, and the 4-pack format ensures you have spares for multiple fixtures throughout your vessel. This product is ideal for cruising boaters, fishing enthusiasts, and vessel owners who spend nights on the water and need comfortable, non-intrusive lighting. The green color preserves red-adapted night vision better than white diffusers, a benefit anyone who has stood watch will appreciate.
