Re: Headlight Hype? or Facts
Despite any irrefutable scientific evidence, I'm going to add a
dissenting opinion--when I replaced the 55/60W bulbs in my 90 with
80/100W bulbs, I got a noticeable difference. It still lights up the
same tiny patch of road, but it does a much better job--it also does a
better job of lighting up the side of the road.
Just my $.02 worth of lighter fluid :)
There is a very fine line between "hobby" and "mental illness."
