Sal,
I don't know what type lights they were, but they were the single, rectangular lights. The issue here was that we were in a parade, headed west at 9 in the AM, the sun was shining on the back of the car in front of you. We were instructed to put on our headlights for the parade. The fact that the tail lights were on all the time made it more difficult to see when the brake lights came on
Some good info coming out on this thread now
