THESE MATRIX BULBS ARE AWESOME.

I just got mine yesterday and damn do they look sweeeet. My turn signals are now DEEP BRIGHT YELLOW instead of amber. My brake lights are much BRIGHTER and they also react much faster when you tap on the brake.

The cool thing about these bulbs is how fast they turn ON and OFF. There's no inbetween like you can see on a regular bulb. Regular bulbs take a second and go from dim to bright. LED's are either instantly BRIGHT/ON or OFF. No in between. For some reason, my turn signals flash faster too, and to me thats just a bonus. It really is a great mod for cheap - takes about 1 minute to install them all too.

And by the way I'm telling you guys about these bulbs from my own free will - I'm not advertising the site. I used some other LED bulbs (APC brand) and they were crap in comparison. Then I found these online, thought they'd work great, and they do.
