I had a quick look at the Rennlist thread (didn't read all 15 pages) and that guy did good work. His solution seems a bit complicated but maybe I'm not aware of all the issues yet. I now know that a rheostat is used and that its resistance varies from 0 to 6 ohms (in a 928 - don't know what it is in an early 911). I only have access to my car on the weekends - I'll make measurements next Saturday.
Does anyone know how Englebert's LEDs behave when the dimmer is used? Wonder what voltage range is swept?
