Antline 1157 BAY15D Amber LED Bulbs Pack of 4 — 1000LM 360° High‑Output, Non‑Polarity 12–24V Replacement

Antline 1157/BAY15D amber LED bulbs are a set of four high-output, plug-and-play replacements that deliver 1000 lumens each for turn signals, brake or marker lights at 12–24V.

These amber LED bulbs are built with 33 high-efficiency 2835 chips arranged for 360° illumination and a non‑polarity base for easier installation. Designed as direct fits for common bayonet sockets (1157, 2057, 2357, 7528 and equivalents), they balance brightness, low wattage, and long running life to modernize vehicle signal and marker lighting.

How bright are these bulbs compared with standard incandescent turn signal lamps?

Each Antline LED produces roughly 1000 lumens while drawing just 3.7 watts, typically several times the visible output of stock incandescent bulbs at a fraction of the power. The wide 360° chip layout spreads light evenly for more consistent visibility from different angles.

• 1000LM per bulb — higher perceived brightness than many OEM incandescent bulbs
• 3.7W power draw — lower energy use and heat generation
• 33× 2835 LED chips arranged for full-angle illumination

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

They are designed for bayonet-style sockets and cross-reference many common part numbers (1157, 2057, 2357, BAY15D, and more), so physical compatibility is broad. The non-polarity design means the bulb will light regardless of orientation, allowing true plug-and-play in most applications.

• Fits 1157/2057/2357/7528 and many equivalent sockets
• Non-polarity base — no need to test for correct orientation
• Compact dimensions: 1.54" length × 0.65" diameter for tight housings

Do I need additional parts or adjustments when replacing turn signal bulbs?

Because LED bulbs draw much less current than incandescent bulbs, many vehicles will trigger the faster blink rate called hyper-flash. To prevent that, you may need an LED-compatible flasher relay or inline resistors when used as turn signals. For marker or brake applications that don’t affect flash rate, no extra parts are typically required.

• May require load resistors or LED flasher relay to avoid hyper-flash
• Works across 12–24V systems — suitable for cars, trucks, trailers
• Rated ~30,000 hours life under normal use

Are these bulbs durable and backed by warranty?

Antline builds these LEDs with a focus on extended runtime and consistent output; the chip and assembly choices reduce heat and prolong service life. The product carries a one-year warranty covering delivery damage and confirmed manufacturer defects, giving added purchase protection.

• Estimated lifespan: 30,000 hours
• Wide operating voltage: 12–24V DC for versatile vehicle use
• One-year warranty for defective items or transit damage

Who is this for: Vehicle owners, fleet managers, and DIY mechanics who want a brighter, energy-efficient amber replacement for turn signals, brake lights, parking lights or side markers. These Antline bulbs suit drivers upgrading older incandescent lamps to LED for improved visibility and longevity, provided any vehicle-specific hyper-flash issues are addressed with the appropriate relay or resistors.
