I include a post below from December of 2011.
I do not do the French lancers, for I specialize in the Peninsular War. But as noted above, enjoy your troops! I have 8 figures each of the Westphalian Chevau Leger with lances (allegedly NOT correct); Lancers of Berg in the rose-colored shako interim uniform; and the Vistulas with yellow-topped Czapaka's. I can use them together to represent a 3-squadron regiment of Vistulas or Bergs. I can also use for provisional light cavalry regiments with 1 squadron of lancers and 2 or 3 of Hussars or Chasseurs a Cheval.
I have 6-8 unpainted French lancers, converted from Stadden Empress dragoons years ago, which were in turn converted to line chasseurs a cheval with the long-tailed habit. Such is what we had to do in the '60's and 70's to have really great figures and some variety! If I paint them, I might use then as dragoons, or a squadron attached to 2-3 other dragoon squadrons.
Writers of the time suggested using a regiment of lancers in a charge, flanked by two of light cavalry to protect their flanks. This gives the lancers a protected advantage in the charge, with their second rank armed only with swords for the subsequent melee.
A fun era, and a fun hobby!
