I'm getting confused over which bulbs we use... I know 1157 are dual filament and used for the front blinkers... and that 1156 are single filament... volkscafe sells 1157 for the front, but lists a 1141 for the rear blinkers... then there are the reverse lights... and the brake lights... need to know so I place an order correctly for led replacements... 

front blinker = 1157
rear blinker bulb = 1141 (or is it really 1157 ? ? ? ....)
rear tail bulb = 1156 (? ? ?) - - - no wait, that bulb is smaller ... ? ? ? 
rear brake bulb = 1156 (? ? ?)
reverse light = 1156 (? ? ?)

thanks... this will help me order the correct led replacements .. . . .
