Only one weight, but several styles.

Mandatory is an amateur digitization of the UK car number plate typeface. A cleaner, well-done version is CP Mono by Tino Meinert. It comes in 5 weights and is, despite its good quality, free as well. See this thread for more license plate type.

Frode already mentioned Lineto. They also have Alpha Headline. It comes in 4 weights, but is available only ‘at the end of 2012’.
Lorenzo Geiger’s Trans-Am is similar.

See also the fonts by Binnenland.ch; Blender, T-Star and Regular, maybe FRAC.
For a more angular direction, check out House United – styles aplenty. Only one weight, but nevertheless 12 styles: Vafle by Tomáš Brousil
