Benlari 2" 1157 Switchback LED Motorcycle Front Turn Signals – Smoked Lens, White Running & Amber Blink

Benlari 2" 1157 switchback LED front turn signals are plug-and-play smoked-lens bulbs that deliver bright amber turn indication and crisp white running light for many Harley models.

These upgraded front turn signal bulbs replace 2" bullet-style incandescent lamps with compact, automotive-grade LEDs housed behind a smoked lens. Designed for straightforward installation, the bulbs combine white daytime/running light and amber turn signal modes in one unit, improving visibility without changing housings or wiring. Built with thermal management and aircraft-grade materials, they target long life and steady performance across touring, softail, dyna, sportster, and similar Harley platforms.

How bright are these LEDs compared to stock halogen bulbs?

Benlari uses high-output LED chips that create a much stronger visible signal than conventional halogen filaments. The bulbs are described as several times brighter in both running and signaling modes, which helps other road users notice your bike sooner in varied light conditions.

• Automotive-grade LED chips for higher lumen output
• Clear amber turn pulses for fast recognition
• White running light option for daytime visibility
• Smoked lens maintains a low-profile look while still allowing brightness

Will these fit my motorcycle and how hard is installation?

These 1157 bulbs are made to fit most 2" bullet-style front turn signal housings and are compatible with many Harley-Davidson models, but they do not fit 3-1/4" housings or 1156 single-contact sockets. Installation is designed to be quick: the bulbs are one-piece and plug into the existing socket, typically requiring no wiring changes.

• Compatible with most 2" bullet-style turn signal sockets
• Not compatible with 3-1/4" housings or 1156 single-contact bulbs
• Plug-and-play — usually under 3 minutes per side
• Check your owner's manual or measure your bulb socket before purchase

What modes and performance features do these bulbs offer?

Each bulb supports a switchback function that provides both white running light and amber turn signal from the same unit, so you get two lighting behaviors without extra fixtures. The design includes thermal control and a durable aluminum body to help maintain consistent output and extend service life.

• Dual-mode switchback: white running / amber signaling
• Integrated heat dissipation for stable operation
• Estimated long lifespan — tens of thousands of hours
• Smoked lens for a sleek, low-glare appearance

Are there electrical or legal considerations to know?

Because these are LED bulbs replacing incandescent lamps, you may notice different current draw which can affect some motorcycles’ flash rate or require a resistor/relay on certain models. Also, local regulations vary on lens tint and color; confirming compliance with your jurisdiction is recommended before installing smoked lenses.

• LEDs draw less current — potential hyperflash on some bikes
• May need resistor or electronic flasher relay on specific models
• Verify smoked lens legality in your area for front signals
• Always test function before regular road use

Who is this for: Riders who want a straightforward lighting upgrade for Harley-style motorcycles that blends a modern LED look with easy installation. These bulbs suit owners of Touring, Dyna, Softail, Sportster, Street Glide, Road Glide, Iron 883 and similar models with 2" bullet front signal housings who prefer a smoked aesthetic, improved daytime presence, and dual white/amber functionality without modifying stock housings.
