I asked LEDTRONICS if they'd provide the site a set of LED replacements for the 1156 (Turn) and 1157 (Parking/Stop) bulbs.
They happily obliged and sent 1 Red 1157 equiv and 1 Amber 1156 equiv for testing. Each is comprised of an encased 24 LED array. 18 LEDS on top facing forward and 6 pointing to the side.
I put them in and took some pitcures. I'll be doing a complete write up for the Reviews Section here soon.
Anyway, here's a list of pros and cons;
PROS
-- Very cool running
-- I LOVE the instant on/off ( NO ramp up)
-- The reds make the taillights match the 3rd brake light perfectly!
-- Very bright
CONS
-- Not as bright from the edges
-- NOT overall as bright as incandescent lamps (Does not fill the lamp housing with light)
-- the light IS directional in output even with the side firing lights.
-- the yellows do not have as bright a glow in the turn signal housing
-- They are pretty pricey (But, you'll never have to replace another bulb)
All in all they are not bad. There are differences but it would have to be up to personal choice to see what you'd prefer.
Here's some PICS for ya and a couple vids.
