I don't know for sure, but I've had a similar occurance on my '87 Ford Escord IV: there was insufficient ground to the headlights, which caused the lowbeams to "draw ground" through the highs. Effectively switching them in series... This also happened when switching over to highbeams; then the lows came on a little bit. If you problem IS ground-related, this could also explain why your taillights don't illuminate. Hope this helps, JAN van de Wouw Goirle, The Netherlands. Thinking Different... Using a Mac...
