When talking about the uniforms of the light cavalry of the French revolutionary army you need to look at the H&C books about the Hussars and Chasseurs a cheval. The first one is the first of a series of three books on the hussar arm of the French Revolutionary and Napoleonic armies. The book about the chasseurs is the first one of a new serie and just out.
Both are great in my opninion and give good short description of the light cavalry but the best part are the pictures of the uniforms of these dashing cavalrymen.
Also a new book, but only partly about French Revolutionary troops, is the H&C book about the various Guides and Guards. When you want to paint ADC's to various marshals or generals from 1792 onwards, this little book should be on the wishlist
Last but not least, an older book but if you are into flags of the French armies from 1791 to 1815, this is the book. It gives plates of a lot of flags of the foot regiments of the FR and Napoleonic armies. Have not yet totalled all the flags in it and don't know (yet) if they are complete, but the wealth of information in it, is great.
