David Beckham -- Cops Swoop In Over Tinted Windows

David Beckham got pulled over in Malibu yesterday ... after cops decided he was too shady for his own good.

Law enforcement sources tell TMZ .. the L.A. County Sheriff's Dept. stopped Beckham's SUV on Pacific Coast Highway because the window tint on the vehicle was too damn dark.

But fear not Galaxy fans, we're told Beckham was merely given a warning and sent on his way.
