I have this same question too.

I believe I have the original OEM bulbs in my '98 base 986. My headlight assemblies are "like new" with no yellowing, scratches, etc. I keep them polished and protected.

I find my headlamps lacking and not as good as other cars.

Is it more of thermals or UV that causes the breakdown on these lenses?

Spending sleepless nights on the internets revealed that we should be using H7u bulbs which have a UV rating designed for polycarbonate headlight assemblies.

So, I would like to upgrade my bulbs from 1998 stock. I do not want to brown my lenses. I want to stay with the stock headlamps with minimal cost, so it will be a H7. My question is.. which one?

I discovered that the "night breaker" OSRAM. Various websites including Amazon state they are "UV safe" for plastic lenses.
