The bulbs on the left are original, the bulbs on the right are the new LEDs. The x45-T bulb is in the outer position, the 3W is in the inner position. The x45-T seems to have better spread in the reflector and the outer tailight position takes better advantage of that. But as you can see from the lens flare, the LEDs both seem to be better than the original lights--at last!
The hardest part of replacing the stock bulbs, is that we have "reverse" polarity on our lighting systems, so most bulbs including the "CAN bus" standard types won't light up at all. One of these is marked non-olarized (will work in anything) the other not marked, but is working.
Sorry, no brake light pix, my foot wasn't long enough to reach the pedal while I worked the camera.<G> I was pleasantly surprised at how bright the LEDs finally are, but my main reason for putting them in is because LEDs actually light up faster than tungsten bulbs, and according to Mercedes that means the guy about to rear end you at highway speed, now gets to stop six feet further behind you instead. Hey, I'll take every advantage I can get over that guy.
