3 1/4 in LED Turn Signals 1156 1157 Socket for Harley - Bright Upgrade

In this review the Updated 3 1/4 in LED Turn Signals are assessed for riders who want a brighter, modern signal that fits many Harley Davidson touring and softail models. The bottom line: these AEEAST-style turn signals pair a switchback halo running light with a center amber turn signal and an integrated red brake/running rear, delivering a clear visibility upgrade over halogen bulbs while remaining a plug-and-play replacement for bikes using 1156/1157 sockets when no load equalizer is required.

Key Features

• Fitment coverage: Designed to fit a wide range of Harley Touring, Road King, Electra Glide, Heritage Softail and select Trike years, which reduces the need to source different parts for each model.
• High brightness LEDs: Built with 60 SMD LED chips for each unit, offering significantly brighter illumination and wider visibility than stock halogen turn signals.
• Switchback mode: Front lights provide an outer white halo for running light and a center amber for turn signal, improving day and night visibility and signaling clarity.
• Integrated functions: Rear units combine running light, brake and turn functions in a compact flat housing for a cleaner rear end without extra lenses.
• Plug n play socket: Uses 1156/1157 sockets for quick installation on compatible models without cutting or splicing in most cases.
• Lower power draw: LED construction reduces electrical load but may require a load equalizer on older Harley models to prevent hyper-flash.

Who It's For

This product is best for Harley owners who ride Tourers, Road Kings, Electra Glides or Heritage Softails from the model years listed and want a brighter, modern signal with combined brake and running light functionality. It suits riders who value straightforward upgrades that keep the original socket type and prefer the visual of a halo running light with a distinct amber center for turn signaling.

Riders of very old Harleys or bikes with 2-in bullet-style turn signals should look elsewhere, and anyone unwilling to add a load equalizer when required should consider standard halogen replacements instead, since resistors are not included and hyper-flash can occur on some older models.

Pros & Cons

Pros

• Noticeably brighter than halogen thanks to 60 SMD LEDs, improving visibility during day and night.
• Switchback halo design provides both running light and amber turn indication in one unit for a modern look.
• Plug-and-play 1156/1157 socket simplifies installation on compatible Harley models.
• Integrated rear brake and running light reduces clutter and keeps a clean rear appearance.

Cons

• Some older Harley models may require a separate load equalizer or resistors to correct hyper-flash, which are not included.
• Not compatible with 2-in bullet-style turn signals, limiting fitment to flat housing applications only.

Our Verdict

The Updated 3 1/4 in LED Turn Signals are a practical, high-visibility upgrade for compatible Harley owners who want a modern switchback look and combined brake/turn/running function without complex wiring. They offer strong value for riders comfortable adding a load equalizer when needed, but those with incompatible bullet-style housings or who want an all-included resistor solution should consider other options.
