easy
if the light is flickering, then it's a connector problem thats easily fixed with some cleaning and the preventive maintenance would be to keep the moisture out of the fixture, out of the connector to the mast and by using liquid tape on the crimp connectors found in back of the assembly by removing it and pulling it out gently. The forward facing light is called the 'steaming light', generally used at night while under power, or to simply light up your sails a little bit to let power boaters and others, without doubt, know your under sail. Because hunter uses so many suppliers, it's hard for anyone to tell you what bulb to get exactly. So, just take the old bulb in and match it or if the bulb is missing, take the entire assembly in and match a fit. (I don't think any boat in the past has ever used a 6volt system or light, but this easy to figure out by reading the voltage on your battery) But I would for one when replacing the bulb, would keep in mind that higher the wattage is, the quicker your battery will run low, will shine further but could also create to much heat inside the sealed casing lessening the bulbs life. So try and get the proper replacement and if thats not easily obtainable, then go with the average wattage that the sales people usually sell for that size boat (heck they probably already know).
