With the Viking Discs LED lights for discs, you extend the season well into autumn. The pack contains 4 LED stickers that you can attach directly to the bottom of the disc. The LED has a 3M sticker, so you don't need your own tape attachments. The round shape also ensures that the impact the LED sticker may cause to the flight path of the disc is negligible. One sticker has four small LEDs. The LED can be turned on and off again and it has three modes: continuously on and two strobe light modes; slow and fast. Attach the LED sticker to a dry disc indoors to ensure the best grip.
