Alot of people right now are asking me what is better for a high beam.
I have had quad 90s up front for a year now.
I have yet to fully compare Hella 60 vs 90mm high beam modules.
Here in the Willamette Valley, Oregon, we have radically varied winter driving conditions.
It common for for air temperatures to hover around freezing.
We are not as wet as Seattle (thank God), but roads are wet all winter.
We get pretty heavy fog and I had never experienced "freezing fog" till I moved here.
Driving here would be a whole lot easier if it were colder.
Couple all that with ODOT not having enough budget to properly paint lines.
Oh and I almost forgot. In the woods, there are deer and wild turkey everywhere.
Stock Fiero lighting blows. The quad 90 set-up is great.
I am going to be running quad 60mm Hella with lows on when bright.
I plan on installing a interconnected fog lights. (will go out upon high beam up)
I actually can legality run more than four lights here.
But, for distance illumination, too much up-close light is a disadvantage.
I think the Freeform Reflector in the 90mm will be slightly better for dry night driving in wooded areas because of the extra "wild" light.
That being said, I plan on running all on at bright and my lows should provide the all peripheral illumination I need.
The biggest reason I will use the projectors for my highs is that I think be able to use them in bad weather more often.

This is my thinking, What is yours?
