The top ones are 194, and BA15 and 1156/1157 are the same thing.
As far as LED for hi beams, I'm gonna wait for LED technology to advance a little further. Right now, they just don't have the light throw that a bulb does on the road. I went to a local shop and compared a Hella baja light to a competitor's LED version and the Hella completely washed out the LED.
I'm ordering 8000k HID for lows and fogs and keeping Silverstars in the highs. I just recently put "eyelids" on the headlights which blocks the top 4 LEDs so I'm replacing them with blue LEDs to create a blue glow in headlight.
Has anybody cracked open one of these headlights? I want to order real CCFLs for the Halo and I need to know which diameter to order.
