Don--can't confirm that. I installed foglights on my 97 GLT wagon and I used the oval lines on the back side to cut the openings for the lights. I never saw any rectangular lines. As I recall, all factory fog lights are round, and cut into the oval opening lines imprinted in the bumper. If you see an 850 with square foglights, it's because somebody bought off market and didn't want to install them where indicated on the inside bumper. The only lights that will fit that oval configuration are the Bosch lights made for Volvo, and expensive. Hence the rectangular mounted lights closer inboard. Dick
