Sealed Beam Replacement

Use a screwdriver to loosen and release the scooter headset screws from underneath. Gently lift the headset upward to give yourself clearance to work. Reach in and pull the wiring connector off the rear of bulb to disconnect it. Use an appropriate screwdriver (flathead or Phillips) to loosen the headlight bracket that holds the bulb in place.

Reach in and loosen the sealed beam bulb from the its bracket. Loosen it the rest of the way with the screwdriver. Pull the bracket off and remove the old bulb. Discard the old bulb or recycle it if facilities are available in your area.

Unpack the new sealed beam and insert it into the holder in the headset. Use a shop towel to prevent touching the bulb with your hand as much as possible. Keep the bulb in place and apply the holding bracket previously removed. Re-insert the holding screws and tighten with a screwdriver. Reconnect the wiring to the back of the bulb and re-tighten the headset top.

Replacing a Removable Bulb

Follow the same procedure as the sealed beam steps, using a screwdriver to remove the headset top and provide clearance. Reach into the headset cavity and place a thumb on the retaining clip of the internal headlight bulb holder. Flip the clip to release the holder.

Pull the holder backwards without disconnecting anything. Provide enough clearance, pulling the holder away from the bulb cavity until you can see the bulb. Grab the bulb itself, twist, and release it from the holder. Discard or recycle the old bulb as needed. Unpack the new bulb.

Hold the new bulb with a shop towel to avoid touching the glass directly with skin (fingerprint oil causes hot spots and premature bulb failure). Push the bulb into the holder, twist, and make it lock into place into the holder. Re-insert the holder with the bulb back into the bulb cavity. Re-attach the holder securing clip to keep the holder in place. Lower the headset cover and re-secure it with a screwdriver.
