To take advantage of a Windex wind indicator at night, you need a light on the masthead so the arrow is visible from on deck.
Davis Instruments now offers a small LED light that’s waterproof and non-corroding to illuminate the reflective tabs under the arrow. It fits under the 10- or 15-inch Windex vane and with different masthead mounts. Retail price is $28.99, and replacement LEDs are $5. Davis Instruments, Hayward, Calif., (800) 678-3669.
