Step-by-Step Replacement Instructions

Step 1 — Safety First

1. Park on a level surface and turn the ignition OFF.
2. Remove the key fob from the bike.
3. Allow the motorcycle to cool completely.
4. Wear nitrile gloves when handling any halogen bulbs.

Step 2 — Headlight

The Sport Glide comes from the factory with a sealed 7-inch Daymaker LED headlight. There is no replaceable bulb — the entire sealed optical unit must be replaced if it fails.

If factory LED headlight replacement is needed: 1. Turn the handlebars for better access behind the headlight. 2. Remove the two T-25 Torx bolts securing the LED headlight to the fork bracket. 3. Disconnect the main wiring harness connector behind the headlight. 4. Remove the old sealed LED unit from the bracket. 5. Position the new 7-inch LED headlight into the bracket. 6. Reconnect the wiring harness connector. 7. Install and hand-tighten the T-25 Torx bolts. 8. Torque bolts to 60-96 in-lbs.

Note: Some owners replace the stock Daymaker with aftermarket projector-style 7-inch LED headlights. Follow the aftermarket manufacturer instructions for those units.

Step 3 — Front Turn Signal Bulbs (1157NA — Amber)

Front turn signals are fork-mounted, bullet-style units.

1. Turn the handlebars to access the desired turn signal.
2. Gently pry off the amber lens cover using a cloth-wrapped flathead screwdriver.
3. Push the bulb in and twist counter-clockwise to release from the socket.
4. Extract the old 1157NA bulb.
5. Insert the new 1157NA amber bulb and twist clockwise to lock.
6. Press the lens cover back into place until it snaps.
7. Repeat on the other side.

Step 4 — Rear Turn Signal Bulbs (1157NA — Amber)

Rear turn signals are mounted on the fender struts.

1. Loosen the base bolt securing each housing to the fender.
2. Pull the housing outward to expose the rear wiring.
3. Remove the rear rubber grommet cover.
4. Push the bulb in and twist counter-clockwise to release.
5. Remove the old 1157NA bulb.
6. Insert the new bulb and twist clockwise to lock.
7. Replace the rubber grommet and verify it seals.
8. Reinstall the housing and tighten base bolt to 60-96 in-lbs.

Step 5 — Tail / Brake Light Bulb (1157 — Dual Contact)

The Sport Glide has a rear fender-mounted tail light assembly.

1. Remove the two Phillips head screws from the tail light lens cover.
2. Set the lens cover aside.
3. Push the 1157 bulb in gently and rotate counter-clockwise.
4. Remove the old bulb.
5. Align the two offset pins on the new 1157 with the socket tabs.
6. Push in and twist clockwise to lock.
7. Wipe the lens interior with microfiber cloth.
8. Reinstall the lens cover and screws. Torque to 15-25 in-lbs.

Step 6 — License Plate Light Bulb (194 / W5W / T10)

The license plate light bracket is mounted beneath the rear fender.

1. Locate the license plate light housing above the plate.
2. Remove the 5/16" bolt or Phillips screw holding the bracket.
3. Pull the 194 wedge bulb straight out of the socket.
4. Push the new 194 bulb straight into the socket.
5. Reinstall the housing and tighten the fastener.

Step 7 — Front Running Light Verification

The Sport Glide uses dual-filament 1157 bulbs serving as both running light and turn signal in the front.

1. Running light uses the dimmer filament; turn signal uses the brighter filament.
2. After bulb replacement, verify both filaments illuminate independently.

Step 8 — Test All Lights

1. Insert key fob; turn ignition to ON.
2. Verify the factory LED headlight illuminates.
3. Test left turn signal — front and rear should flash amber together.
4. Test right turn signal — same verification.
5. Press front brake lever — tail light should brighten.
6. Press rear brake pedal — same brightening confirmed.
7. Verify tail light maintains dim running glow.
8. Confirm license plate light is illuminated.

Step 9 — LED Upgrade Considerations

When upgrading halogen positions to LED on the Sport Glide:

1. Headlight: Already LED from factory. Some owners upgrade to aftermarket projector or halo-style 7-inch LED units.
2. Turn Signal LEDs: The Softail CAN bus may hyper-flash with low-draw LEDs. Install Harley-Davidson load equalizer (p/n 68194-04) per turn signal pair.
3. Tail/Brake LED (1157): Most 1157 LED bulbs work plug-and-play on the Sport Glide Softail platform.
4. Polarity: Flip LED bulbs 180 degrees if they do not illuminate.
5. Error Codes: CAN bus may log lighting faults for un-resisted LED retrofits. These clear after cycling ignition with proper resistors installed.

Step 10 — Final Verification

1. Confirm all lens covers are fully seated and weather sealed.
2. Check all fasteners are tightened to specification.
3. Verify no tools are left on or near the motorcycle.
4. Take a short test ride to confirm proper lighting performance in real conditions.
