Dim Headlights

I have replaced my old bulbs with Phillips +50% jobbies, but they've hardly made any difference. I can't drive much above 40mph on unlit roads without full beam because I can only see a few feet in front of the car.

Is this the best I'm going to get without splashing out for the borderline illegal types? Could it be that they are simply angled too low?

My bulbs have always seemed very dim in the F as well... Be interested to see if anyone has any suggestions!

Mine aren't that much better, but again they are nearly 9 years old so could be age. From what I've read though, the F lights are generally quite poor.

I do alot of driving on unlit roads too and I'm glad the light nights are coming.

Quite a common problem on F headlights is the headlight inner chrome bowl deteriorating over time and becoming dull, which reduces the headlights output.
The fix is either to replace the whole headlight or to take them apart and get the inner bowls re-chromed, which I believe costs around 70-80.

Bit more on the subject here.

That's a shame, I got good results from fitting the Philips bulbs.

I might re-chrome the reflectors yet though, my N/S light does not have a destinctive beam pattern so the olf reflector could be deteriorating a bit.

I had mine fail on one head light for its MOT so replaced them with trophy ones, they are a little better but not much, then I tried 100w ones, yeah I know they are illegal so I dipped them to compensate, anyway they didn't work for long both bulbs got shaken to death within 2 weeks, it seems the higher wattage the more fragile they are so I'm down to 80w again .......so far so good

When I had my first 'F' I always found reversing everywhere at night improved visability...

I'm surprised that you're still struggling with those bulbs fitted. I too had great success with the +50 philips bulbs. At the same time I found that the headlights were very badly adjusted ( both pointed down and to the centre of the road). Try yours against a flat surface -wall/garage door. If they've got a good pattern i.e. each dip shows a clear horizontal cutoff on the right hand half of the beam, then reverse away from the flat surface in a straight line, watching the junction between the right and left half of each beam- the junctions should stay the same distance apart( basically the distance between your two headlights), but should drop down the wall as you reverse away from it, but not too quickly.
The proper adjustment also made a big difference to my nighttime visibility as well. So much so that I can say that I have good headlights now, both on dip and main beam.
If your beam pattern is bright but does not show a good cutoff pattern, it could be the glass internal lens is mucky/fogged. Take the lamp to pieces and clean the glass lens.
If it's just that the light output is poor it could be that the reflector has dechromed as mentioned in a previous post.

p.s hope that makes sense.
