I have a stock headlight bulb out and I want to replace both sides. What the latest greatest replacement bulb for the stock housings?
I agree! I have run 80/100 Hellas and a HD relay wiring harness (LMC Truck .com, about $30) in my Impalas', Ford Excursion and Lincoln mark VII LSC, for over 10 years. I am very happy with the visible improvement in illumination. Used properly, no one flashes at me. (Not a dramatic improvement, but significant).I run some 80w/100w Hellas. I don't recommend them if you haven't upgraded the harness though. Also they are technically offroad only.
Brighter headlamps could get you into hot trouble | DrivingWhen most HID conversion kits are installed on reflector style headlamps they simply wash the road ahead in a very broad and glaring pattern that causes great risks to oncoming drivers.
The retailer also supplies this caveat to all shoppers; “Every jurisdiction has its own rules and regulations governing the use of automotive lighting. HID lighting systems that are supplied with the vehicles from the factory are DOT approved. There are currently no HID conversion kits available from any source which is DOT approved if installed outside of the automotive factory. Moreover, in the United States, this is not street legal for use on public roads. In Canada, a similar but less defined clause applies.
If you want a bulb for a daily driver or are on a budget the brightest bulbs of any product line may not be for you. The brightest ones usually have the lowest life span.(hours)
The GE Nighthawks (not platinum) that we have been using have been a good compromise between good light and lasting more than a year of daily driving. The mandatory day time driving lights on some cars are the low beams so these bulbs are on at all times. The brighter ones would last 6-7 months.
So when you make your choice find the information on how many hours they run. Some are very low.

I would like to provide a argument against HID and LED retrofitting:

I just bought a pair of these last night....I run some 80w/100w Hellas. I don't recommend them if you haven't upgraded the harness though. Also they are technically offroad only.
