I have a 2003 Lowe Seanymph Deep V center console 16' boat. The post lights are by Perko. The bow light is a Perko three pin female receiver. I have lost the light. I purchased an Atwood bow light at Bass Pro in Cinci last week. It says that it works in all three and two pin receivers. I put it on the boat and it does not work. Upon inspection, I found that the light does have three pin holes, but only two have contacts. Here is the question- Is it a defective light (I have changed the bulbs with a known working bulb) or will this this light not work in the Perko receiver? The dilema is that in order to exchange it to see if the light is defective, I will have to drive four hours to Cincinnati. I would hate to exchange it when it is not the light, but the compatability. Any insight would be appreciated.
