My idea sounded like a good one. Replace the navigation lights, red, green and clear, with LED bulbs. My thought was that it would save a LOT of drain on the battery. Well, I did some research and found out it's a bad idea. There are already some companies that make these. Prices ranged from rediculous to outragious. We are talking $65 to $600 for the red/green combination. At first, I couldn't understand why. I realized that they were being made overseas and were made mainly for yaghts and big sailboats, but that wasn't enough to justify those prices. Then I found out what is going on. While the LED's work great in flashlights, the weak link in them are the way they cannot handle any variance in amps or voltages. I had noticed that flashlight LED's were not found normally in a rechargable model. It is the recharging that kills their lifetime. Voltage spikes and the surges that happen when a charger is hooked up, will reduce their life to fractions of what they are designed for. This happens a lot in boat usage and has minimal effect to incandesent bulbs. The high dollar LED lights for boats is because a built in modulator is installed with them. They must be able to calm down even a variance of .125 volts. That's not cheap. Oh, well, there goes my idea down the drain, of making a fortune selling boat LED's.
