AUTOONE 1157 LED Bulb Red - Pack of 2 BAY15D Projector Replacement, High Output & IP68 Durability

These are AUTOONE upgraded 1157 red LED bulbs (pack of 2) — high‑output BAY15D replacements built with a projector lens, aircraft‑grade aluminum body, IP68 sealing, and plug‑and‑play fit for tail, brake, reverse, marker and parking lights.

Replace dim or slow incandescent 1157/2057/2357/7528 bulbs with these high‑lumen, long‑life LED units engineered for clear red signaling. The bulbs combine a focused projector optic with 360° visible LEDs, an integrated IC driver and a one‑piece aluminum housing to increase light output, thermal management and durability in wet or dusty conditions.

How bright and visible are these AUTOONE 1157 red LEDs at night?

These bulbs are designed to deliver significantly more visible red light than standard halogen or basic LED replacements. The projector lens concentrates light for a recognizable stop/marker signature while the surrounding LEDs create full 360° coverage for side and rear visibility.

• High luminous efficiency for stronger red output
• Projector lens for focused beam and sharper stop signal
• 360° LED arrangement improves side visibility
• Works well for brake, tail, marker and reverse applications

Will these bulbs fit my vehicle and are they easy to install?

These AUTOONE bulbs use the common BAY15D/1157 base and are intended as direct socket replacements for 1157, 2057, 2357 and 7528 applications. Installation requires no drilling or wiring modifications — they are plug‑and‑play in standard sockets, though some vehicles with strict canbus systems may need a resistor or flasher relay to prevent warnings or hyper‑flash.

• BAY15D (1157) base fits most compatible sockets
• No polarity design for many US and CK sockets
• Plug‑and‑play: no drilling or rewiring required
• Optional load resistors or relay may be needed for some canbus systems

How durable are these LEDs and how long will they last?

The AUTOONE 1157 red LED bulbs are constructed from one‑piece aircraft aluminum to dissipate heat efficiently, and they include an intelligent built‑in IC driver to stabilize performance. They are rated to last up to 50,000 hours and carry an IP68 rating to resist dust and moisture in harsh driving environments.

• Rugged aluminum body for improved thermal control
• Integrated IC driver for steady output and protection
• IP68 sealing to prevent water and dust ingress
• Estimated service life of up to 50,000 hours

What should I expect regarding electrical compatibility and warnings?

The bulbs are designed with non‑polarity to simplify fitting in many sockets, but vehicles with sensitive CANbus systems can detect lower LED resistance and may report errors or hyper‑flashing. If warning lights or flicker occur, adding a compatible load resistor or an LED‑friendly flasher relay typically resolves the issue; customer support is available for troubleshooting.

• Non‑polarity works with most US and CK sockets
• CANbus vehicles may require resistors or relay to stop errors
• Contact customer support for installation guidance and solutions
• Pack of 2 for dual‑lamp applications (brake/tail pairs)

Who is this for: The AUTOONE upgraded 1157 red LED bulbs are aimed at car and truck owners who want brighter, longer‑lasting red lights for tail, brake, marker and reverse functions. They suit DIYers and professional installers seeking a durable, weather‑resistant LED upgrade that improves visibility and reduces replacement frequency, provided you confirm CANbus compatibility before fitting.
