Off-Shore Tackle has come out with night lights for your planer boards that will catch you more fish and keep you safer after dark. They are shock resistant and made of high impact shatter-resistant plastic. They run on two 1.5 volt 'button-style' batteries and they say "for maximum battery life allow batteries to rejuvenate 2 hours or more after 6-8 hours of continuous use". They are easy to install--just unscrew the flag on your current Off-Shore planer boards and replace them with the OR32 Night Light 2. They come 2 per pack in either red or green/chartreuse for $22.95. Only complaint I have is that they should have come with one red and one green in a pack--that way you could have the the red on your port side and green on your starboard side so other fisherman would know what side of your boat is facing them and give you more distance.
