I've wanted to put LEDs in my panels but it hasn't been high on the list... The issue with LEDs are that they are not omni-directional. My 67s have alot of illumination done through the edge of clear plexiglass (light pipes). LEDs just shoot straight up. Not sure of the answer. As for the heat of 168s. Dunno. The heat will be directly proportional to the current draw so, if 168s pull a significant more amount of current, the heat will be significantly more. Try this... Take a 158, impede airflow around it (a towel, in a small box or etcetera), put 12V across it and measure the temperature. Do the same with a 168 and see how much hotter it is. >I was wondering why my instrument panel bulbs for the backlighting seemed >to be a little dim (typical of old 60's car...I think).
