For the 2006 Toyota Land Cruiser, the low-beam headlights use 9006 bulbs, while the high beams use 9005 bulbs. The daytime running lights also use 9005, so the high-beam and DRL applications share the same bulb size. The fog lights are listed for 9006 LED bulbs.
Other useful exterior fitments include 1157A bulbs for the front turn signals and front side markers, 7440A bulbs for the rear turn signals, and 921 bulbs for the reverse lights. The parking lights and license plate lights both use 168 bulbs. Rear side markers use 168NA bulbs.
Interior applications include a DE3175 dome light, 2821 courtesy light, 2721 glove-box bulb, 194 interior bulb, and 168 map light. The ash light may use either 2721 or 74; compare the replacement with the original bulb before ordering. These listings are organized by function, so confirm the existing bulb and socket when replacing less common interior applications.
