I have a 2010 Street Glide that uses the factory rear turn signals as run brake and turns, from the factory. Nobody seems to know whether it is an 1156 or 1157. I would have thought 1157, but others have said otherwise. Can somebody who has pulled theirs tell me which it is. I am not at home to look. I think I ordered the wrong bulbs and want to cancel before shipping. I'm converting my lenses to smoked. Thanks

 

Rear = 1156 single filament
Front = 1157 dual filament

 

google says 1156, I would go with uncle google.

 

I would think it has to be 1157for the dual element. 1156 only has a single element I believe. Are they using led lights now though* that could be a different deal. Wish i was certain for you but I can't guarantee it.

 

doghair, are you sure? The rear 2010 signals are also the brake and run lights right from the factory.

 

They are 1157 dual element on the 10 SG

 

thanks

 

I stand corrected. 1156 are standard on the models I've dealt with using the run/turn/brake mod where the voltage is changed via the under the seat module for the single filament, looks different for the SG with no taillight.

 

I tried replacing my front blown turn signal on my 2011 limited with an 1157...it would stay lit, but would not blink when I pushed the blinker switch....I installed a 2057 and it now works fine...I'm assuming it would be an 2056 for the rear. YMMV

 

oops, my bad, did not realize you were asking about a SG...Sorry
