Not all headlamps are waterproof, but many models come with varying levels of water resistance. If you anticipate using the headlamp in wet conditions or near water bodies, it is advisable to choose a headlamp with a higher IPX rating, indicating increased water resistance. Waterproof headlamps offer added durability and protection against rain, splashes, and accidental submersion. Check the product descriptions or specifications to determine the water resistance level of a headlamp.
