You guys still aren't understanding the term "intersection warning"... As in warning when you are entering or "nosing into" an intersection... Don't get me wrong, I LOVE my MirrorBeams, and the SOS Intersectors are a sweet looking light, but they aren true intersection warning... MirrorBeams and Intersectors are technically Mid-Level warning. True intersection warning is something mounted as far forward as you can... Depending on your mirrors, they are a good 4+ feet behind your front bumper, therefore are not very productive as intersection warning...
