• Tight fitting end caps slide to expand or contract the length of the bulb to fit many fixtures
• Highest quality components - really!
• High light output
• Reduces energy consumption — current draw of only about 0.1A
• Incredibly reliable — usually never need replacing
• Note: White LED bulbs should not be used behind colored lenses in nav lights, as they will not produce the required brightness; only the corresponding colored LEDs should be used in nav lights with colored lenses
