【Answer】 93
【Analysis】The requirement is to find the lamps that are not lit after the pulling, which actually means finding the lamps that were pulled once. From 1 to 200, there are 66 numbers that are multiples of 3, and 40 numbers that are multiples of 5. Those that are multiples of both 3 and 5, i.e., multiples of 15, are 13. Therefore, the lamps that were pulled only once are $66+40-13=93$ (explanation)
$15, 200$ lights are on, each controlled by a pull switch, numbered in sequence as $1, 2, 3, 4, \ldots, 200$. Pull the switches of the lights whose numbers are multiples of 3, then pull the switches of the lights whose numbers end in 5. After pulling, the lights that are off are $\qquad$exhibit.
