Frequently Bought Together


The BAY15D plug-and-play LED replacement bulb is suitable for RV and boat applications. The 360° beam angle reduces hot spots and provides a wide viewing angle for all-over light emission. The stock bulb cover encloses the LEDs and gives the bulb a traditional look. Designed to last 30,000 hours- 25 times longer than incandescent bulbs- they are ideal for cabin lights, navigation lights, and dome lights.

Product Details:
  • Polarity Sensitive (+/-)
  • 12 VDC
  • 3 year warranty
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.
3 Years
Super Bright LEDs, Inc. offers a 3-year warranty to protect against manufacturer defects and malfunctions. If you experience failure of an LED or other component not caused by negligence, abuse, unauthorized repair or disassembly, we will replace the product within the warranty period. If the same product is no longer available, a product of equal value may be substituted. Read More

2015 Yamaha SR400 Tail/Brake bulb

I purchased a Yamaha SR400 with one mile on the odometer. After riding around, and performing a once over, I decided to check the bulbs for intensity. At 100ft away, I could tell immediately that the stock incandescent tail bulb was inadequate. I ordered this bulb, as it was the best fit(found I had more room). I snapped a photo each, of pre/post-LED running and brake light action. These bulbs snap on faster, and are brighter on both accounts. I feel safer knowing that these lights can be seen. As you can see in the photos, just the running LED is brighter than the activated stock bulb.

I will be using these bulbs in amber for my front marker/turn signal.

So so...............

Not nearly as bright as I wanted. In fact, I can't tell the difference from the incandescent they replaced.

Same size as a normal 1157 bulb

Installed these in the brake lights on a motorcycle trailer with a Harley light assembly. They fit where the (1157­RHP28­T:Red) bulbs are to long and are brighter than the original incandescent bulbs. I wish more of the bulbs were built like these, the glass cover over the LEDs helps protect them from dust & moisture. I recommend these bulbs to anyone looking to switch to LEDs.

Very good. But not as good as I hoped.

Bulbs arrived quickly and in good shape. They appear to be high quality. They are sized well and I appreciate the glass over the actual LEDs. I purchased two to replace the bulbs on my motorcycle's brake light.

Unfortunately, they are not as bright as I was expecting.

In both of the attached images, the new LED bulb is on the right and the old bulb on the left. In the dimmer ("running lights") photo, the brakes are not applied. Here you can see that the new bulb (on the right) is slightly brighter. In the second photo (brakes applied) they are about the same with, possibly, a small edge going to the old bulb (on the left).

I'm keeping them as the LEDs snap on faster than the incandescent bulbs. But at $20 per unit, I was expecting a far greater improvement.
