Contact The Button Junction today to find out how you can add one or two blinker lights to many of the custom buttons available on our web site. Blinkers add a fun and visual aspect to any design that will stand out in a crowd. Draw attention to your message, organization, product or event with a flashing, red LED light attached to a battery with a convenient on/off switch. Blinker lights are a perfect way to add emphasis, fun and flair to your button.
