Our dual color Red & White Switchable Constellation replacement LED bulb is made specifically for the standard dome lights and square ceiling lights found in most boats and RV's.  We offer in all the standard bulb base styles, including Bayonet Single-Contact (BA15S), Bayonet Double-Contact (BA15D), T10 Wedge (W2.1x9.5d), Festoon (SV8.5), and Bi-Pin (G4). Custom bases or pigtails by request.

This drop-in bayonet LED 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 low intensity red output that is more than enough to see down below at night. This prevents the loss of night vision and avoids disturbing others. Imagine being able to convert any 5" or 6" dome 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 digital latching technique within the bulb's microprocessor 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. Reverting to red mode is done by simply waiting more than 3 seconds after turning off the light.

Our unique 15-LED matrix is designed to fit perfectly in the standard 5" and 6" dome lights like those made by ABI, AAA, West Marine, and Cabin, among others. The bulb features 3 Red and 12 Warm White triple-emitter SMD LEDs, along with a peel-and-stick foam mount backing that makes installation easy, even on concave or irregular surfaces. For curved surfaces, simply taper the edges of the adhesive foam backing to meet the shape of the housing. Our emitter board also has a special notch cut-out for the socket, so the bulb fits perfectly centered.

    Red White LED dome light

    Posted by Unknown on 9th Aug 2017

    This turned out to be quite useful. I only bought one to try but have since switch the cabin dome lights out to this type.

    Excellent Product

    Posted by Dean Benjamin on 22nd Feb 2017

    I have purchased numerous LED arrays from Marinebeam and I have been please with all of them and with their customer service. This application required a festoon connection and this solution was terrific. This was for a cockpit application in which I wanted the option of either red or white light and this fit the bill. I did have to slightly modify the circuit board to make it fit but it worked out well.

    Brighter than I expected

    Posted by Joe on 11th Jul 2016

    I just replaced all the 12vdc light bulbs in my CR 38 with LED's. There are two that had dual bulbs, red and white and I figured that they would only be white now. I was happy to find that there was a red and white replacement . The toggling from red to white is a nice feature keeping it simple. Both the red and white are brighter that I expected. The installation was a breeze. It could not have gone better.
