Is the C70 hard on head lamp bulbs?

Thank you. I owned a 2008, but never had this problem. But then again, it wasn't driven that much either.

4 years newer as well, take a look at the plastic connectors that plug up to the bulbs, bet you will find signs of heat,, distorted or partially melted connectors! Replace the female wire terminals and add dielectric to the male bulb terms.

That's exactly what's happening. Ok, will do. Thanks!
