You did not specify:
1. If the lights have gotten dimmer with time
2. If the lights are the same as ever, but you are now more sensitive to them
3. If the lights have always been crummy

The headlights on USA-model V70s and S70s are crummy, seriously inferior to the genuine Hellas installed on the equivalent cars in Europe. I know this because I switched headlights with the European ones. Buying the genuine European Hellas proved to be quite an ordeal. I searched and searched and never found a supplier in the US or Canada. Finally, a friend brought them back from Sweden for me in his suitcase. Total cost was around $700. The so-called E-code from FCP are from Taiwan and are much less expensive. Another hint: you need to replace the entire headlight unit. The European glass alone will not do it. The reflector units are different.

I do believe they lose their intensity with age. We replaced our 850 bulbs with Sylvania Silverstars and the difference is great. No special wiring required. I didn't believe they could lose so much intensity, but have seen it too many times. Kind of like over rated use of flourescent lights in the home----they lose a lot in a rather short period of time.

If you've been dissatisfied with the intensity of the original equipment lights since you got the car, then the alternative lights should be considered. If the lights were once okay but have now lost their former intensity, look for an electrical problem. They do not go dim except perhaps right before they fail and if failing, not likely both at the same time. Have your battery, charging system and battery connections checked thoroughly. Even a small voltage or charging current deficit will weaken the intensity of otherwise normal lighting.

i just bought E-code lenses for mine. i love them. check them out, they are around 90 pair and fit well. you can get them on ebay and also at the store direct.

if they are likethe 850 they are just not good...fit osram silverstars or the phiolips equivilent bulbs for lights that work...
