Product Description

THIS IS THE LARGER 15-LED VERSION OF OUR 9-LED SWITCHABLE RED/WHITE G4 BULB. It is 45mm (1-3/4") in diameter, so should be used in larger fixtures. It works great in 4"-7" overhead dome lights. With the bayonet adapter, it will work in bayonet domes as well.

After two-years of development, we introduce our new patented Red & White Switchable side-pin G4 LED bulb. This drop-in G4 bi-pin replacement features two modes from the same bulb! It can function as either a Red bulb, for preserving night vision, or with a quick flick of your existing switch, it can morph into a high-output super-bright Warm White bulb. No need for changing out fixtures or wiring.

When initially switched on, its output comes from the three center RED LEDs. This provides a nice soft red output that is more than enough to light to see really well down below at night. This red start-up mode is really handy to prevent the loss of night vision, and avoids disturbing others down below. It is your choice whether you want Red or Warm White, and the control is all done using your existing switches.

Imagine being able to convert any light in your boat to a red output with just a quick flick of the switch. No need for big double bulb fixtures and 3-way switches. This is all accomplished using a patented digital latching technique within the bulb's sophisticated electronics. The bulb senses each toggle of the switch and latches into the Warm White mode if the switch is toggled off-on within 3 seconds. To revert to Red mode is a simple off and back on with a 3 second delay.
