Well, I am sure compatible LED replacement bulbs could be had, but I am not sure they would look good.<p>I know in my MB days, most cars had a "bulb out" sensor and indicator in the dash, much like our R's do. Most LED's don't draw that much current and set off the bulb out indicatior ... can be overcome with resistors wired in line.
Like these:<p><A HREF="http://cgi.ebay.com/ebaymotors/3156-12-LED-Lights-Red-2-Bulbs-TurnSignal-BackUP-Tail_W0QQitemZ8061017758QQcategoryZ33713QQrdZ1QQcmdZViewItem" TARGET="_blank">http://cgi.ebay.com/ebaymotors...wItem</A>
These bulbs wouldn't look good on the R. What I would really like to see is some Cadillac style LEDs (I am not referring to the entire tail light like the Deville, just the small individual square transistors integrated in a nice design across a portion of the brake/turn signals)<p>BMW also has them as well as the Audi A8 for example. I don't like the large LED lights on the G35 or RX330.
Did a quick yahoo search: (old article)<p>Hewlett-Packard Company today announced that the 2000 Cadillac DeVille, available in showrooms this fall, uses HP SnapLED1 technology for its entire tail-lamp and brake lighting system.<p>"We're pleased to offer HP's exceptional light-emitting diode technology, which offers drivers several advantages," said Ed Zellner, Cadillac DeVille chief engineer. "Cadillac and HP are putting science to work for the safety of our customers."<br>.<br>.<br>.<br>Further, LED taillights provide a much smaller optical package, which results in a far more compact assembly and reduced encroachment on trunk space. Instead of a large bulb backed up by a sizable parabolic reflector, the LED light combines an intense light source with a miniature reflector in a tidy package. This helps achieve the DeVille's spacious 19.1 cubic feet of trunk space. The extra efficiency also reduces power consumption by 80 percent when the brake lights are lit.<p>LED light also provides extra design flexibility. Each taillight has 72 LEDs that can be arrayed to create new and interesting visual appearances. Sixteen lights provide the taillight function; four are used for the side marker light; and the remaining 52 are illuminated (with the taillight LEDs) during braking. In the DeVille, the lights are arrayed to provide a strong vertical line, but there also is excellent visibility from the side view.<p><B>SnapLED interconnects the LEDs via a system of thin metal strips that serve as electrical conductors, supports and heat sinks.</B> Because the LEDs themselves are clinched to the metal frame, there are no wire leads in the assembly whatsoever, reducing the likelihood of open or short circuits.<p>"The automotive industry has embraced LED advantages such as reliability, design flexibility and safety since the 1980s, and its adoption of LEDs for high-mount stop lamps has been excellent," said Adil Munshi, automotive marketing manager for HP's Semiconductor Products Group. "Now, as HP LEDs get brighter and much less expensive, we are seeing many innovative new designs for full combination lamps -- those that combine turn, tail and stop signals -- on more vehicle platforms."
Here is a better article that talks about SnapLEDs:<p><A HREF="http://www.lumileds.com/products/line.cfm?lineId=5" TARGET="_blank">http://www.lumileds.com/products/line.cfm?lineId=5</A><p>SnapLED<br> <br>Today's automotive exteriors call for a vision that goes beyond the ordinary. With LED technology from Lumileds, you can deliver unique lighting designs and original styles.<p>Lumileds SnapLED assemblies for exterior applications are compact, and can be shaped to any contour. By enabling a more streamlined structural approach, they give you the freedom and scope to define new forms that are more individualized, and expressive. SnapLED assemblies allow lighting designers to create stylish and futuristic "signature" looks.<p>SnapLED products use the world's brightest LED material, Lumileds' TS AllnGaP technology, to radically reduce the total quantity of LEDs typically required to perform the tail lamp functions.<p>The thin design eliminates the need for deep cavities and reduces vehicle body costs. Innovative fastening techniques offer limitless styling flexibility.<p>A New Dimension <p>SnapLED modules can be formed to accommodate complex three- dimensional shapes.<p>This Lumileds development allows you to design uniform light sources - even around corners, without restricting your design<p>Snap LED 150 is designed to be driven at 150 mA<br>Snap LED 70 is designed to be driven at 70mA<p>Benefits:<p>Fewer LEDs Required <br>Lower System Cost <br>3-Dimensional Array Design <br> <p><IMG SRC="http://www.lumileds.com/images/productphotos/snapled.jpg" BORDER="0"><p>They talk about 30 degree and 85 degree radiation patterns. What would be our application? What would be involved in puting together an array of these lights to fit our brake lights and turn signals? Probably not cheap but it would completely change the way your back end looks.
One thing for sure, looking at the size of our break lights and how high they are. They will surely be blinding bright if you fill them up with arrays of LED's.<br> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0">

The cool thing (pun intended) is that you don't have to fill the entire brake area with the LEDs...you can create a really neat design pattern that suits your tastes.<p>I would love to create something for the brake lights and turn signals front and back.<p>I was looking at their prices and it would cost about 20-25 bucks for an array of 60...according to their PDF file about custom automotive lighting, that is around the maximum amount that will be needed for each application (even possibly half for the turn signals each).<p>It would still run about $200 just to get all the LEDs you need and then incorporate them with resisters to trick the computer. And then you have to figure out how to place and stick them inside the tail lights.<p>Anyone up for it?
I would like to see how they look while on, as well as a picture close up of them and from the backside of the tail light to see how they are hooked up.<p>Is there some type of resistor for each LED cluster?<p>I will try and contact lumileds for some info to see if it is possible and if it has been done by a joe blow like me.<p>Thanks

You could always try something like these:<p> <A HREF="http://www.spiderlite.com/" TARGET="_blank">http://www.spiderlite.com/</A> <p> <IMG SRC="http://www.spiderlite.com/img_home/gallery-5ARM-OPEN.jpg" BORDER="0"> <p>The collapse down to fit into the light fixture then open up. Expensive though.
I have these on my SRT4. Were only $150 and they are MUCH brighter and cooler looking (especially since my car is black). I think someone would be able to retro-fit something in the stock housing...its just is the demand high enough to keep the costs down because the retrofit could become very pricey I bet<p><IMG SRC="http://myspace-654.vo.llnwd.net/00516/45/61/516481654_l.jpg" BORDER="0">
Here is one side while lit. I can take a pic with both sides lit if needed.<p><IMG SRC="http://i10.photobucket.com/albums/a139/tmdc98/000_0223.jpg" BORDER="0"><p><br>Edit: Better pic of rear housing to be posted later.
