Jim Dawson was kind enough to give me 2 LED lamps for my S10 after he spoke on the subject (many months ago).
These are amber colored turn/parking lights for the front. The

Jim told me i'd probably have to change out the old (1992) thermal flasher for a new digital one because the LEDs use so much less current, the old ones think the bulbs are burned out and don't blink :-)
i happened upon this great article for modifying the blink-rate of a digital flasher in case i need to:
http://www.instructables.com/id/Automotive-electronic-flasher-rate-modification.It's a simple modification, replacing a fixed resistor with an external variable one to determine/adjust the desired blink rate. Perhaps the blink rate could be synched with the tempo of the currently playing song
Here's one of the pictures from the Instructable to whet your whistles:
