LED lights?
super exciting topic I know! Well I thought I'd share what I learned in case others are curious about LED taillights. I wanted to try one for two reasons.
1) Faster response
2) Hopefully brighter

I read a lot of mixed experiences, many saying they aren't as bright, LEDs are not as bight off angle, and reflectors aren't designed for them, and blah blah, so I wanted something pretty bright.

Got one of these to replace the stock bulb in stock housing
1157 3.8 Watt 36 Red LED

stock 27W ~402 lumen (on high) bulb on low, off angle, no background light

As you can see, photos don't show a big difference in brightness, though to two different sets of eyes, the "high" (brake on) was brighter. And the off angle on high or low didn't seem to be a problem. Looked like a pretty normal light to me. And it responds noticeably faster. So I'm content.

Some things to look out for if you're looking to buy:

Include "SMD 5050" in your search. You don't want this type with the through-hole LEDs

And there are a few SMD sizes, most often used are 3528 and 5050. 5050 is a larger size and approx 3x the output per LED.

As you can see, 36 of them is somewhere in the range of what you're looking for to emulate or beat a 27W stock bulb. If you look around, you can find some that are longer with 50+ SMD5050s on there, that would be sweet as long as it'll fit in your housing. So check how much room you have available.

Match LED color to what you want to see. While the stock light might be white/yellow, and then red or amber due to the lens, a "white" LED is really 3 different color LEDs and much more of the light is just going to get filtered out by the lens.

It doesn't seem like any reputable manufacturers are making the things (they're probably not legal for street use), so yes, it's going to be super china brand. Oh well. Fortunately there's not much to the product, mine appeared pretty well made. But much of what's out there would be woefully underpowered if you don't know what you're looking for.

For turn signals, yes, you'll probably have to put a resistor in-line or buy a bulb that already has that or the turn signal will flash fast since the bulb isn't drawing much power. At least in may case, for a brake light, this wasn't necessary.

i have two 12 LED strips (<!-- m --><a class="postlink" href="http://www.customdynamics.com/knight_rider_led_light_bar.htm">http://www.customdynamics.com/knight_rider_led_light_bar.htm</a><!-- m -->) for the brake lights (FYI the brake lights isnt "on" in that picture)

I also have a white 3 LED license plate light (<!-- m --><a class="postlink" href="http://www.customdynamics.com/step_lights.htm">http://www.customdynamics.com/step_lights.htm</a><!-- m -->) i hid in the set up. sorry for the crappy pic... i snapped it on the way to work. i think they are fine to use. i know the state troopers think other wise, at least on the I-95 section of the state, the I-66 troopers leave me alone.

I'll try to take some day time pictures of the set up when i get home.
