Custom Dynamics Insert Direction indicator

Manufacturer reference: GEN-4-RR-1157

The Custom Dynamics GEN-4-RR-1157 indicator inserts provide a sleek look and clear signalling at the rear of your motorcycle. Designed to replace a 1157 bulb, these inserts feature 48 red LEDs per unit arranged in two distinct zones: an outer ring of 24 LEDs that serves as a halo position light and 24 central LEDs dedicated to stop and indicator functions, offering visible contrast during alert phases.

• Socket compatibility: 1157 (bayonet)
• Colour: red
• Functions: dual filament (position / stop + indicator)
• Number of LEDs: 48 per insert
• Mounting position: rear

Installable as plug-and-play on 1157 sockets, these inserts are designed for vintage/classic builds, touring bikes, and roadsters seeking a neat and readable finish. They integrate particularly well on Harley-Davidson customs — for example, Road King, Road Glide CVO, or Street Glide CVO — when the original equipment accepts a 1157 socket. A product by CUSTOM DYNAMICS, ideal for replacing or modernising your rear lights while maintaining a discreet and effective aesthetic.
