What Is a 3 BL Sedan Hatch Interior LED Light Kit?
A 3 BL Sedan Hatch interior LED light kit is a set of direct-replacement bulbs that swap into the factory dome, map, reading, vanity, trunk, glove-box and footwell sockets without cutting or rewiring. AutoKitShop lists 10 3 BL Sedan Hatch LED kits covering model years 2003 to 2018. Kits for this model run from 2-piece to 11-piece sets. Each bulb is rated at 300 lumens and roughly 3x the brightness of the original incandescent lamp, at a fraction of the current draw, with a 50,000-hour service life. Kits are supplied as complete sets with the correct socket adapters, so nothing needs to be ordered separately. If a bulb does not light on first fit, rotate it 180 degrees, because LEDs are polarity sensitive. Colour options are white (6000K), ice blue, warm white (3000K) and purple.
