The 370 Series LED lamps are designed to be an easy-to-fit trailer lighting solution that can be fitted in a range of orientations. Box trailers need lamps to fit in a horizontal orientation and shine the number plate light across the trailer, from the narrow side of the lamp; while boat trailers need a number plate lamp that shines out of the wide side of the lamp downwards. In a design solution, these lamps have number plate lamps fitted to one short and one long side of the right hand lamp, with the installer simply connecting whichever of the tow number plate function wires that suits their aplication best. The fact that they look good, have cable length options, are submersible, and E-marked, makes them a first choice for many trailer builders.
