Battery Installation
Water marker lights, including the WL-1, are shipped without batteries.
- Hold the light with the strobe down and make sure the circuit board is fully seated in the black frame holder, circuit contact area facing upward.
- Seat a 6 volt lantern battery (alkaline is best) with spring/coil terminals in the remaining half of the case/housing.
- Invert the battery inside the case/housing over the circuit board and rotate the half of the case holding the battery until threaded HAND TIGHT ONLY.
Use ONLY a 6-volt, spring-post style lantern battery (alkaline preferably). Forespar does not supply batteries.
