Handling & Installation Tips

   Use exactly 12 V DC per lamp to avoid early burnout or dimming.
2. Insert Carefully Into Slide Base
   Slide the lamp straight into its socket—avoid twisting or sideways force to prevent contact damage.
3. Avoid Excessive Vibrations or Shock
   Although rugged, incandescent filaments are sensitive; mount in secure housing to minimize mechanical stress.
4. Check for Secure Seating
   After installation, gently wiggle the lamp to ensure it’s fully seated and making good electrical contact.
5. Store Spare Lamps Properly
   Keep backups in anti-static, padded packaging to avoid glass damage or bending before use.
