LED Marker Lights ( ST1300 )
Updated 4/14/2007: Finally gave up and reinstalled the stock bulbs. Too much heat for LEDs in the headlight housing. Too bad. I really liked the look of the LED bulbs. I had the same issues trying there in my Mazda RX8.
Updated 8/6/2006: The Autolumination (http://www.autolumination.com/) bulbs are also starting to fail. I guess there's just too much heat in the ST headlight for any brand of LEDs. :(
Updated 5/5/2006: I've given up on the SuperbrightLEDs (http://www.superbrightleds.com/) and have switched to the Autolumination 194 LEDs (http://autolumination.com/194.htm). So far, so good.
Updated 8/24/2005: I recently had several of the LEDs in these arrays fail so I ordered some replacements from SuperBright. I also noticed that they came with a one year warranty. SuperBright <was> going to replace them until they realized I was using these lights in an application that subjected them to the heat of the headlight bulbs. They claim that LEDs cannot withstand this type of heat for a long period of time. I went ahead and bought some of their 'next generation' bulbs to give it another shot, but was told I would not be getting free replacement bulbs under warranty.
WLED-X6 (http://www.superbrightleds.com/cgi-bin/store/index.cgi?action=DispPage&Page2Disp=%2F1157.htm) LED 12 volt bulb from SuperBrightLED.(http://koczarski.com/ST1300/LEDMarkers/P0002981w.jpg)
Has the same type of connector as the stock bulbs.(http://koczarski.com/ST1300/LEDMarkers/P0002982w.jpg)
The bulbs look pretty blue, but in an HID type of way. Very bright!(http://koczarski.com/ST1300/LEDMarkers/P0002984w.jpg)
