As to that, I would suggest doing a simple test: have your drive team stand under the goal, about where the driver station of your opponents would be. If they can't see when the light is on and pointing in their direction, assume that you'll be blinding your opponents, which could fall under R08, part A of the blue box, which would cause a nice chain reaction leading to a redesign. Note that it doesn't have to be designed to limit vision, just used to, or just cause an unsafe condition. Get the light so that it doesn't blind the drivers, then have them go to their own station's distance and see if they can see it. Repeat until you get it aligned.
