Abstract: A light system is disposed to be located on top of guide poles on either side of a trailer. The light system is in-line with the guide pole and may almost appear to be a part of the poles. The elevated light system allows for the brake lights to be more easily seen by following drivers and it normally keeps the brake lights from being immersed in water when the trailer is used in loading or unloading a boat or other marine craft. Additionally, in comparison with lights attached to the side of a guide pole, the in-line nature of the light system makes it less likely that the light will be knocked off or damaged when backing a trailer into a tight garage opening. Furthermore, a tell-tale lens is located opposite the primary lens and it allows the driver to be able to verify that the lights are working.
