LEDGlow’s Expandable LED Interior Kits feature four 15 inch tubes with a total of 120 ultra bright, wide angle LEDs. Our expandable interior led lighting kits feature multiple lighting effects, and are expandable to include an additional two 9 or 15 inch tubes. The included lighting effects feature strobing, fading, and chase modes along with a sound activation mode which will allow the interior kit to react to the music playing inside of the vehicle. This kit also includes a controller bypass function allowing your kit to be powered on from a switched source such as headlights or a door opening.
