Here at BCF we have a large range of Trailer lights and are available in either complete kits, pairs or replacement lenses & bulbs from manufacturers including Ark Corp. They are easily mounted and remember when wiring to use tinned copper wire, solder joins and heat shrink to extend the life of the wiring. Trailer lights are designed to be submersible in water. If you are looking for low heat and low power draw then LED lights would be beneficial. The major benefit of LEDs is that they have a 100000 hour bulb life, making them virtually maintenance free. LED trailer lights are waterproof, extremely bright and are resistant to shock and vibration.
