I had a similar situation, where a car in front of me (a Fairlane no less) had no brake lights at all, and nearly ended in tears. The thought that occured to me is how to prove the lights weren't working after you've smashed them up with your bonnet. "They were working before you hit me".
At any rate, what's happened has happened... I had a similar accident with my old Ea, ran up the back of a little Pulsar that pulled out in front of me. Are your headlight assemblies actually broken, or just the glass? I was able to simply buy new glass for the headlights from Ford quite cheaply, polish up the assembly and just re-fit them.
Do you have clear front indicators on the EA yet, and if not, do you want them? Now would be a good time to upgrade to them, if thats what you want...you can get them for 50 bucks each from Ford, ask for the GT indicators. If not, then the cheapest way is to simply go for a tour-de-wreckers with some tools and go hunting for what you want... otherwise search the usual auto places, and always check Fords prices too, sometimes they'll suprise you and be cheaper than the aftermarket gear.
Good luck with it all.
