Those 2357 bulbs don't work on my bikes turn signals

If you're using them on the rear, that's the wrong lamp.  You need a single-filament lamp on the rear, an 1156 or other xx56 lamp should work.  Only the front signals use the xx57 lamps.

  Ok they do work on the front they are 28.5/8.3 watts stock is 21/5 watts,with in 20 feet they seem hardy differenced  in brightness,maybe at a couple hundred feet they would show up more.
