I swapped just the two illumination lights in my cluster with LED's from LEDLight.com (these: http://www.ledlight.com/t10-wedge-5-ultra-bright-smt-led-light.aspx)

My #1 fuse insta-blew with the LEDs in. Replace fuse, poof again. Put the old incandescent lights back in, and so far it's fine.

Any ideas? Thanks.
