Hey Frank:
I can tell you from experiance that there is no LED style bulb that is brighter than the stock Bulbs that I have found. (Don't waste your money)
In order to fit the 1157 bulbs, you are going to have to do some alteration to the sockets as they take 1156 bulbs.
And clear lenses are legal & dot approved. They are on the new Bandits. Like Paul says, as long as the fronts are amber when luminated, and the rears are either amber or red when luminated. (They must be red on the rear if you convert to running lights)
You can buy the clear lenses at clear alterantives. In fact if I can recal, they are even stamped DOT approved.
