Differences Between 1157 and 1156 Connectors
1157 Connector
The 1157 connector features LEDs that emit a bright red for running lights and an even brighter red for brake lights. When the turn signal is activated, all LEDs alternate between bright red and brighter red, enhancing visibility at all times.
1156 Connector
In contrast, the 1156 connector ensures that when the turn signal is activated, all LEDs flash bright red, providing increased visibility.
Which Connector Should You Choose for Your Motorcycle?
For Bikes Without a Rear Brake Light: If your motorcycle does not have a brake light on the rear fender, the 1157 style signals are suitable. These signals function as running lights, brake lights, and turn signals, featuring two contacts at the base of the bulb.
For Bikes With a Rear Brake Light: If your motorcycle includes a brake light on the rear fender, you will need the 1156 style signals. These have a single contact at the base of the bulb.
