Setup and Installation
- Safety First: Ensure the power supply to the fixture is turned OFF before attempting to install or replace the bulb. This prevents electrical shock.
- Verify Compatibility: Confirm that your light fixture is designed for a 12-volt power supply and accepts a BA15S (Single Contact Bayonet) base bulb. Using an incompatible bulb or voltage can cause damage or malfunction.
- Handle with Care: Hold the bulb by its glass envelope, avoiding contact with the metal base if possible, to prevent transferring oils from your skin, which can shorten bulb life.
- Insert the Bulb: Align the two pins on the bulb's base with the slots in the fixture's socket. Push the bulb gently into the socket and twist it clockwise until it locks into place. Do not force the bulb.
- Secure Connection: Ensure the bulb is firmly seated in the socket to establish proper electrical contact.
