LED replacement bulbs can fit numerous boat and RV applications such as navigation lights, cabin lights, dome lights, tail lights, brake lights, reverse lights, turn signals or side marker lights. This 1157 dual-contact, dual-function bulb has 27 LEDs (Epistar 5050 SMD) that create a 360° viewing angle for better, allover light emission with reduced hot spots. Produces up to 290 lumens at 6200K. Tower-style design with a BAY15D 15-mm bayonet base for easy plug-and-play installation—just twist to lock in place. The energy-efficient bulb operates within a wide 10-30V DC range and is designed to last 30,000 hours on your motorhome or boat—25 times longer than incandescents. Available in cool white, amber and red. Not sold in pairs. Price per bulb.

Important Notes - Please read before purchasing:
  1. Your vehicle may require an LED compatible Flasher or Load Resistor. LED brake/tail lamps will not flash with most stock flasher units due to their extremely low current draw. Try our Vehicle LED Bulb Finder to find a compatible flasher for your vehicle. Please See More LED Car Bulb Notes
  2. For best results the LED color should be the same as the lens color. If bulb is behind a clear lens, use the appropriate color for turn and brake light functions. Please See More LED Car Bulb Notes
  3. If your daytime running light application serves multiple purposes, this bulb will most likely not work for your vehicle.
  4. To protect LEDs in marine applications, it is advisable to use a 12 VDC line conditioner to compensate for voltage irregularities common in marine low-voltage systems.

Much Better

I originally bought a different bulb and it was no better than the old incandescent bulbs. I got these instead and they are so much better. I made a video, but it is too big to load here. I knock these 1 star only because the cost is so high for just one little bulb. But they do look and function much better.

Not plug and play

Tried to fit this globe into my 1968 Corvette (front blinker and parker) but globe wouldn't engage. I had to remove the light fitting from the vehicle and modify the base of the globe holder with a Dremmel so that lugs would properly engage. The globe holder is approximately 1mm too deep for the new LED. I hope I don't have this problem with the other external lights on the Vette.

LED Light Staff Response

Some vehicles have sockets that are designed to include the sloped sides of the envelope on an incandescent bulb to allow proper fit. LED bulbs may not be able to fit in those sockets.
