Straight Bar LED's - BRIGHTER?




I dunno which is brighter, however. I always though the C's LED bars (same unit they're using on the new E's) were a little more yellowy and/or dim looking, but I dunno. Did you see them side-by-side? Would be interesting to see that.
It wouldn't be shocking if they upped the wattage. The 2011 C/E's with halogens already look bad enough with those yellow lights and whiter LED's (but the yellow-y look of the 2011 C LED-bars actually match the halogens better), so it'd be downright goofy for P1 cars with even brighter LED DRL's.
Damn! And I was 100% content on the slanted LED's. Now, I'm still partial to its design, but gotta live with it not being as bright, oh well (how bright do they really need to be.... At least the Xenons are the new 5000K stockers!).

I can't comment about the gray one but depending on it's opacity, a yellow/orange bulb would probably make that legal as well.
Federal Motor Vehicle Safety Standard 108 requires the sidemarker lighting. The requirement is two-fold - an amber light source emitting light meeting an SAE standard for "amber" AND an amber reflector. The requirements for the rear are identical except that the color has to be red.
Accordingly, while the clear one "might" meet part of the standard when used with an amber bulb (assuming an amber bulb is available that meets the SAE standard for "amber") it clearly
fails as it does not have an amber reflector.OTOH, you could glue on some amber reflective tape onto the bumper to meet that requirement and use the clear sidemarker
Accordingly, since we must legislate to the stupidest amongst us, the amber front, red rear requirement was born.
Why with a reflector? To address those idiots that drive down dark roads at night with their lights off.
While this is a Federal requirement and states cannot waive it, it is the responsibility of states to determine what they will check for during periodic inspections.
Accordingly, there are a few states like PA, that actually check for operational sidemarkers and will fail cars not meeting the requirements.
Other states couldn't care less, but - in theory - a violation is "operating an unsafe vehicle" and the operator could get stopped, ticketed and (again in theory) have his car impounded and towed.
From my observation, the housing of the straight LED has a little more complex design -- the LED bulbs sit deeper inside the housing, making the LED not as in-the-eyes when view from an angle (probably is deisgned on purpose, so the LEDs wouldn't blind other drivers in adjacent lanes.)
Also, the lens-cover of the LED housing has a slight diffusing effect, making the LED lighting with a little more sophisticated feel.
At last, in my car with the P2 Package, the straight LED actually changes its intensity depending on the headlamps -- if the headlamps are On, the straight LED would be automatically changed to dimmer intensity (probably also a design-on-purpose, so the LEDs wouldn't be too bright to other drivers at night.)
Again, just my observation.
With best regards,

Numerically, a higher number indicates a "colder" color temp going more into the blue spectrum. As color temps get colder, you actually need more output to get the same number of lumens but the blue tint gives the impression of being brighter - hence the comment in the article
"This light colour is in keeping with normal human perception patterns, and as such conveys an impression of greater brightness to the eyes, thus reducing the strain on the driver,”
I suspect that MB also upped the output of these lamps to meet requiremens as the blue light may fool the brain but it won't fool the machine.
MB appears to be really pushing the envelope on this - extremely interesting stuff.








- should be illegal!?
