Why Upgrade Your Motorcycle Turn Signals?

Turn signals aren’t just a legal requirement — they’re one of the most important parts of staying safe and visible on the road. Many stock halogen signals are dim, slow to activate, and prone to burnout. By upgrading to LED motorcycle turn signals, you get:

  • Brighter output: LED signals shine 2–3x brighter than halogen bulbs.
  • Instant activation: LEDs light up instantly, giving drivers more reaction time.
  • Longer lifespan: LEDs last up to 30,000+ hours.
  • Custom style: Smoked lenses, halos, sequential patterns, and bullet housings.
  • Plug-and-play convenience: Easy DIY installation with no splicing.

Types of Motorcycle Turn Signals

When shopping for signals, you’ll see several different types. Here’s what you need to know:

Front vs. Rear Turn Signals

Motorcycle front turn signals are typically white running lights that switch to amber when turning, while motorcycle rear turn signals are amber or red and may also function as brake lights.

Universal Motorcycle Turn Signals vs. Model-Specific

Universal motorcycle turn signals fit many bikes but may require adapters or load resistors. Model-specific kits are designed for direct fitment on Harley or Indian bikes.

Styles of Turn Signals

  • Bullet style: Classic Harley look, round and iconic.
  • Bar-end signals: Integrated into handlebars, great for café racers.
  • Flush mount: Low-profile, sleek design for sport bikes and customs.
  • Sequential: Modern flowing pattern that sweeps outward.
  • Switchback: White daytime running light that changes to amber when signaling.

Choosing the Best Motorcycle Turn Signals

Harley Motorcycle Turn Signals

Harley motorcycle turn signals often use 1156 (single-function) or 1157 (dual-function) bases. Many modern Harleys also have CANbus systems, which can cause hyperflash without a load equalizer. Eagle Lights offers plug-and-play Harley LED kits with everything included.

Indian Motorcycle Turn Signals

Indian motorcycle turn signals require model-specific fitment. Eagle Lights makes dedicated kits for Scouts, Chiefs, and Roadmasters — all plug-and-play with no splicing required.

Universal Kits

If you’re building a café racer or custom bike, a universal motorcycle turn signal kit can be adapted to your wiring. These are popular for custom builds but may require minor modification.

Installation & Compatibility

One of the most common concerns riders have is installation. With Eagle Lights kits, it’s simple:

Plug-and-Play LED Upgrades

No cutting, no splicing. Our plug-and-play motorcycle turn signals are designed to fit right into your existing housings.

Load Equalizers & Hyperflash

When switching to LEDs, some bikes experience “hyperflash” (signals blink too fast). This happens because LEDs draw less power. The fix is simple — install a load equalizer or use a CANbus-compatible kit.

2-Wire vs. 3-Wire Setups

Understanding your wiring is key. 2-wire signals are usually turn-only, while 3-wire setups combine running light + turn signal functions. Eagle Lights makes both styles for Harley and Indian bikes.

Troubleshooting Common Issues

Fast Blinking (Hyperflash)

Install a load equalizer to correct hyperflash after upgrading to LEDs.

Dim or Flickering Signals

Usually caused by poor grounding or loose connections. Double-check your wiring harness.

Compatibility Problems

Always confirm your bike’s socket type (1156 vs. 1157) and whether it uses CANbus. Eagle Lights makes CANbus-ready kits to prevent error codes.

FAQs About Motorcycle Turn Signals

  • Are motorcycle turn signals universal? Not always — Harley and Indian often require specific fitment, but universal kits are available for custom builds.
  • Do I need a load equalizer for LED signals? Yes, unless you purchase CANbus-ready kits from Eagle Lights.
  • Which is better: amber or red signals? Amber is generally more visible, especially in the front. Rear can be red or amber depending on preference.
  • Can I use my turn signals as running lights? Yes — many modern LED kits function as both running lights and signals.
