Installed all
Thanks for all your thoughts.
I installed both high and low beam bulbs this morning. I am out of practise when it comes to such complex, hi-tech, 21st century mechanical stuff, but I really thought I could change four light bulbs. However, consistent every Vette I have ever owned, there are -- or at least, I have -- uninteresting unexpected problems.
I found that I had to raise both headlight assemblies fully to even just barely be able to squeaze my hand and wrist behind to reach the bulbs.
And then there was the passenger-side low beam.... It was very difficult to remove. When I got it out I learned why. At the factory, it had been forced and inserted in such a way as to have bent the steel fingers of the bezel that hold it. There is a piece of the snap-in ring that is pointing out, was pin-sharp, and wasn't holding the old bulb. This made installing the new bulb in the damaged bezel almost impossible.
After about an hour I did get that low beam in a somewhat solid position, but it will not twist fully and is therefore not aimed properly.
The important thing is that the bulbs are much whiter, brighter, and my vision is clearer. Night driving is usefully clearer than with the old yellow lights. C5s might be seen more readily by other drivers.
This was a definitely a worthwhile upgrade. --- I hope that one low beam bulb stays locked in its seat.
Thanks,
Peter
