How to Replace a Horse Trailer Light

As with any other vehicle, the light bulbs on a horse trailer will periodically burn out. Over time, the reflective plastic covers that protect the lights may also become damaged, or may need to be replaced. Just as with regular cars and trailers, replacing light bulbs and plastic covers represents a part of the regular maintenance of a horse trailer. Replacing blown light bulbs and the light covers is a simple repair job that can be done at home.

Instructions

    • 1

      Remove the plastic light cover. Typically you will need a screwdriver to perform this task, but some trailer light covers snap into place using tabs or clamps. If you do not see any kind of screw holding the plastic in place, it probably just snaps in and out and you should be able to gently squeeze and wiggle it until it comes loose.

      Horse trailer light bulbs are more similar to vehicle light bulbs than to the traditional bulbs you have inside your house; the vast majority of bulbs are held in the socket by prongs--they do not need to be twisted in. Grasp the light bulb gently by the plastic or metal at its base and pull it straight out to remove it.

      Determine what kind of replacement bulb you need. Hopefully, you will already have a replacement bulb on hand, but if you do not, you should be able to locate one by taking the bulb to your local auto parts store and finding a similar replacement.

      Plug the new bulb into socket. You should line the prongs up with the socket and stick the bulb straight in.

      Replace the plastic cover. If you are replacing the plastic as well, screw it or snap it back onto the trailer in place of the old plastic.
