If you go to this page of the website http://www.superbrightleds.com/cgi-b...rake-turn.html and look at the bulbs in the 2nd selection box under the ones you purchased ,at the bulbs 1157 Dual & 1156 Single Contact BA15 High Power SMD LED Automotive Bulbs
with the LED's not only on the top but also the sides of the bulb you'll see they are a "360 degree Viewing Angle" bulbs which throw light all the way around the fixture, but they cost quite abit more then the ones you bought.So most likely it was a misunderstanding from the buyer and not the bulbs fault  hope this helps and congrats on the super amount of posts you have made!

All of your information is about 12 volt bulbs. There are, indeed, a lot more choices for 12 volt. Since I'm at 6 volt I got one choice only on this page:
http://www.superbrightleds.com/cgi-b...57-x12-24V.htm I bought the only bulb available for tail/brake light for 6 volt. I did have a choice between 15 degree viewing angle and 100 degree viewing angle. I bought the "wide angle" 100 degree viewing angle bulb and that's what I got.
