  • Confirm your spa is a Hot Spring Spas brand unit before ordering
  • Check that your existing light assembly accepts a drop-in bulb replacement rather than requiring a full fixture swap
  • Inspect the lens and gasket on your light housing — replace if cracked or brittle to prevent water intrusion after install
