I got my replacement/plug-n-play bulbs for my 914 guages and small VDO guages from
www.superbrightleds.com . It took 15 min to swap them out and 45 min. to sit and listen to a cd and look at them.
The BA7s is a direct replacement for the standard old Porsche/VW guage light and the 74 is the small VDO wedge type.
I went with red because that is the only other color other than black and silver on my car.
Sweet and eazy and only cost me $11 plus shipping ($6) to do a 914 3 guage set and 5 small VDO guages. :agree:
