- Wear Gloves: Handle the new bulb with a clean, lint-free cloth or gloves. Avoid touching the glass envelope directly with bare hands.
- Remove Old Bulb (if applicable): Carefully remove the old R7s base bulb from its spring-loaded socket. Gently push one end into the socket and pull the other end out.
- Insert New Bulb: Align the R7s pins of the new bulb with the corresponding slots in the fixture's socket. Gently push one end of the bulb into its socket, then compress the spring-loaded mechanism to allow the other end to slide into place. Ensure both ends are securely seated.
