I am sharing info on this because I have been asked how are they any more questions and I will be glad to answer them...

I will "brake" it down like this.
The bulbs are very nice.
I put mine in my rear turns only to stay legal in the rear you only can have red or amber,I still have a regular #1156 bulb in my front,so by having this combo,it
triggers my turn signal bulb blown fast blink but it is ok and in fact it looks real cool,just looks like from the front or back people will say hey man you have a blinker
blown but not true at all....

In the rear on the #1157 it is dual filament so what happens is with your park lights on only the 4 middle led's light up and then when the brake is applied the rest of the
circular outer part of the bulb lights up......they glow a neon,deep blood red look very,very cool and different even behind the factory red lens.....they look very
different and noticeable especially at night on a dark street,they aslo shine real bright like a normal brake light in the daytime too......get you some you will be satisfied.....
