Yes, you can use fishing lights during the day, but their effectiveness may vary. Fishing lights are primarily used to attract fish in low-light conditions, such as at dawn, dusk, or nighttime. However, during the day, clear water conditions and the position of the sun can make it difficult for fish to notice the lights.

If you decide to use fishing lights during the day, consider the following tips:
1. **Choose the Right Color**: Green and blue lights tend to be more effective in attracting fish during the day as they penetrate water better than other colors.
2. **Depth Matters**: Use the lights at deeper depths where fish might seek shade or cooler water. This can help in attracting species that are less active in the heat of the day.
3. **Use in Combination**: Pair fishing lights with other techniques, such as chumming or using live bait, to increase your chances of attracting fish.
4. **Try Cloudy Days**: On overcast days, fish may be more willing to come to the surface, making it a good opportunity to use lights.

In summary, while using fishing lights during the day can be less effective, with the right approach and conditions, you may still see some success!
