Re: Boat Trailer lights
LED's produce less heat then any other source of light currently on the market, however they do get hot, the brighter they are the hotter they get, the LED's in cop car light bars are the hottest I know of and have heat sinks attached to them or some other way to disperse heat. LED's are encapsulated in plastic rather then glass so they can handle the heat much better plus the entire LED circuit board can be encapsulated in silicone or plastic or whatever the manufacturer decides is appropriate for the application. Obviously the more you use your brakes the hotter they get, but LED's (As brake lights) just don't generate that much heat and disperse the heat better as well, when you look at your LED brake lights the more LED's you see the colder they are, the LED's that are 1/2" or bigger in size are the brightest and generate the most heat. Once you install one of these lights have your child stand on the brakes and touch one, then go over and touch the other brake light with the bulb and you will instantly see what I am talking about. The bulb may burn your finger so beware.
The problem with LED's has always been the amount of light they could generate, but recently the technology has made some pretty huge advancements that make them very bright but at the same time very low power and much better longevity when compared to typical light bulbs. Just to give you an idea, remember the days when Cops would use rotating lights in their light bars? They would draw 40 amps or more when all lit up when they were brand new, and obviously with all those motors(some light bars had 10 motors in them) running as they got older they would draw more and more, today's light bars draw much less, plus now once the car has expired the light bar still draws the same power as when it was new, and can be reinstalled on the car that replaces the expired one, they have that kind of longevity.
