Product Information

Full details

The motoLEDy BAY15D LED bulb set is an essential upgrade for owners of vehicles imported from the USA or Japan, designed to simplify the conversion of red rear turn signals to the orange light required by European standards. Featuring 57 high-efficiency SMD 2835 LEDs and an integrated CANBUS system, these bulbs provide superior brightness and error-free compatibility for modern vehicle electronics, though users must be aware that they are intended strictly for off-road use and are not certified for public road traffic.

FAQs

Can I use these bulbs on public roads?

No, these bulbs are designed exclusively for off-road use and do not meet the ECE requirements for public road traffic.

Will these bulbs fit my vehicle?

These are designed to replace P21/5W and 1157 style bulbs. Please verify your vehicle's current bulb type before purchasing.

What is the primary benefit of the CANBUS system?

The CANBUS system communicates with the car's computer to simulate the power draw of a traditional bulb, preventing false 'bulb burned out' alerts on the dashboard.

How long do these bulbs last?

These LEDs are rated for up to 50,000 hours of operation, significantly outlasting standard incandescent or halogen bulbs.

Are these bulbs compatible with both 12V and 24V systems?

Yes, they are compatible with both standard 12V automotive systems and 24V systems found in larger vehicles.

Troubleshooting

Dashboard shows a bulb out error

Ensure the bulb is fully seated in the socket; if the error persists, check that the vehicle's electrical system does not require an additional load resistor.

Bulb does not illuminate

LEDs are polarity sensitive. Remove the bulb, rotate it 180 degrees, and re-insert into the socket.

Pros and Cons

Pros

  • Eliminates the need for complex rewiring of imported vehicles
  • Bright 2000lm output improves signal visibility
  • CANBUS system prevents dashboard warning lights
  • Extremely long service life compared to halogen bulbs
  • Simple plug-and-play installation

Cons

  • Not road-legal for use in public traffic
  • Requires professional or careful installation to ensure correct lens output
  • Limited to off-road applications

Setup, Compatibility & Care

Installation follows a standard 'plug-and-play' procedure. Simply access the rear tail light assembly, remove the existing P21/5W or 1157 bulb, and insert the motoLEDy LED unit into the socket. Due to the orientation-sensitive nature of LEDs, if the bulb fails to light up immediately, remove it, rotate it 180 degrees, and re-insert. Since these bulbs generate less heat than halogen equivalents but are high-power units, ensure the assembly is dry and the socket contacts are free of corrosion to maintain a solid electrical connection over the bulb's 50,000-hour lifespan.
