All,
I have replaced all 6 turn/stop/running lights with these LED replacements:
1157 LED Bulb - Dual Intensity 1 x 3 Watt High Power LED w/ Reflector Lens | LED Brake Light, Turn Light and Tail Light Bulbs | LED Car Bulbs | Super Bright LEDs
and
1156 LED Bulb - Single Intensity 1 x 3 Watt High Power LED w/ Reflector Lens | LED Brake Light, Turn Light and Tail Light Bulbs | LED Car Bulbs | Super Bright LEDs
I found them to be at least as bright from all angles and definitely brighter looking straight on. A little pricey, but not outrageous and they fit the sockets/lenses very well (even better than the standard bulb as the glass just about bottoms on the plastic when turning into the socket)
. I do think that some of the other variants are very directional, but the reflector added to this one appears to do the job well. I also think that a number of the other styles listed on the site will just not fit the sockets.
Selecting the color to match your lens color as suggested worked for me as mine are amber and red only (no clear ones).
