A single screwdriver is all you need to ensure a clear view of the road at night.
Most Harley-Davidson motorcycle headlights mount directly onto the triple tree, the clamp-like structure that supports the front fork and handlebars. This placement allows the headlight to turn in the direction the motorcycle is steered, providing enough light to illuminate a darkened curve in the road. When the headlight bulb burns out, remove and replace the bulb through the headlight’s easy-to-access location on the triple tree. While there are some differences between the ranges of machines offered by Harley-Davidson, the job is straightforward and can be performed on most of the company’s motorcycles.
1. Remove the screw at the bottom of the outer headlight trim ring using a Phillips-head screwdriver. Pull the trim ring off the headlight shell.
2. Remove the inner headlight adjustment ring using a Phillips screwdriver. This step applies only to Road King models and models that have a fully enclosed headlight cowl.
3. Pull the headlight lens out of the headlight shell. Pull the rubber boot off the rear of the headlight lens. Unplug the electrical socket from the headlight prongs on the rear of the lens.
4. Squeeze the bulb-retaining clip, then pull the clip away from the bulb. Pull the bulb out of the headlight lens.
5. Grasp the new H4 headlight bulb by its prongs, avoiding all contact with the glass portion of the bulb. Slide the bulb into the headlight lens, matching the raised portions of the bulb’s base with the notches cut into the lens. Squeeze the retaining clip and lock it into place over the base of the headlight bulb.
6. Plug the electrical socket into place over the bulb prongs, then push the rubber boot into place. Push the headlight lens into the headlight shell, placing the Harley-Davidson logo on the front of the lens in an upright position.
7. Reinstall the inner alignment ring, if it was removed earlier. Reinstall the outer trim ring.
