Seemed like it would be easy to figure out which bulbs go where but there are 4 door, 2 map, 2 vanity, I'm assuming and then two that fit the same way but are longer. I put them in the license plate but maybe they go in the mirror or vanity lights? Not sure how we are supposed to know. Also the dome light didn't fit. It was too long. I tried sanding the points down but still wouldn't work. I drove to NAPA and got one for $10. So my $18 set suddenly increased to $28 plus hassle of driving to get it. The odd part is the Napa fit better but still seemed a little too long. I have it jammed in and it works but the points aren't where they belong. I wouldn't recommend this set since you'll have to spend more money on another dome light. This was a 2012 4runner
