Ice fishing Tip up lights
They are really bright, the white ones seem the brightest, but I have all 4 colors and they can be seen from a long ways away. I like running multiple colors so I know which tip up is up just by the color of the light. I will put the red closest, blue middle, and white furthest. Then if I am in the cabin or shanty and look out I know right away which one is up.
Check out this light for just $8. Awesome LeD Light that is bright enough to see your spindle at night! //https://www.ebay.com/itm/TIP-UP-LIGHT-Highly-Visible-LED-TIP-UP-LIGHT-in-Red-White-Blue-or-Green-/202155393064?_mwBanner=1
