Discussion
driving along the other day thinking my lights are crap.
so i had a look around on hear to see that this seems to be the case with all cerbs.
so i got hold of some of the new phillips 80% brighter bulbs thinking this will make it better.
so i take out my old ones and to my discust one is 80/100w and the other 90/100w so both not for road use.
any way new bulbs fitted 55/60 as should be. i would say about the same but not good.
anyway my point is that my friend has a set of these in his seat and there much better in that.
any one no why ?? could it just be bad reflectors??
if any one can help would be good as i would like to be able to see where im going

Sorry mate - but why are you complaining about the wattage when it is restricted to limit the light output.so i take out my old ones and to my discust one is 80/100w and the other 90/100w so both not for road use.

Which you are trying to increase by fitting 80% brighter bulbs??
An old law that they forgot to get rid off when the Eurocrats agreed to allow anything legal in one country to be legal anywhere else.
Range Rover lights I hear are approved in Holland or some such place that allows these lights, so the fockers can blind us all the time!
I have the 4 pot projector Tuscan style mod to mine.
The dip is a rather poor standard 55W, but the main is HID!
They give RR drivers a taste of their own!!
Isn't it usually the case to have dips as HIDs, and mains as normal? The theory being that you use dips a lot more, so you'll get more benefit.
Anyway, those 'brighter' bulbs are only brighter by drawing more wattage through the lighting system. Now, given TVRs decision to use some pretty thin cabling, I'm not sure I'd want to up the current going through it! This way also be why the bulbs aren't too bright, because the wiring can't cope with anymore current? Though, I would have thought if that was the case, the wiring would have started a fire by now.
The above is one of the reasons why I decided against using 'brighter' bulbs in my Tuscan style headlights, and instead have opted to use a HID kit with ballasts and relay.

Sorry Jammy B but this is not correct. Providing you fit the same wattage bulb it draws the same current. I use Osram Nightbreakers and they are fine. The difference is the gas and filament, not the wattage.As per the OP, I removed high wattage bulbs and fitted the new lower wattage ones to very little effect. I believe the original bulbs that were incorrectly rated contributed to reflector deteriation and a broken lens
Fit a set of HID's - Easy to fit and they make a massive difference.
Cue the replies from all the Vicars, Good boys and Saints who will tell you that you are very very naughty if you fit them, as strictly speaking they are illegal. (As is going over 70mph and removing your Cats - which obviously they would never dream of doing

sorry forgot to mention that before i could fit my new bulbs i had to replace the wiring plugs that had melted because of the increased current draw from the over powered bulbs thats the only reason i was complaining about them.
I improved mine with:a) brighter standard wattage bulbs (mine are xenon but not HID)
b) new reflectors,
c) higher voltage at bulbs.
To increase voltage use the existing supply to operate a powerful relay which switches in a new supply via thicker cable direct from the battery. Protect your wiring with in line fuses in waterproof holders. The relays and fuses can be hidden under the headlights. Use protective wrap for the new wiring so you don't go up in flames!

Probably bad reflectors/bad adjustment? Mine are slightly rusty at the bottom but I have phillips 50% brighter bulbs and don't have a problem. Not as great as the modern, very bright lights, but still pretty good.
Bad wiring set up... remember those wires go all the way back and forth on the Cerb due to the location of various parts of the electrical system. I'd also want to check the earthing points, made a huge difference on ours. The real solution was to fit HID's and a seperate circuit/fuse at the front I believe? Dads an Electrical engineer, so he has a better idea of these things than I do.alderley said:

You are not increasing the open circuit voltage. It still uses the same battery. You are just trying to reduce losses. All of which increases the effective energy expended in the bulb.
Sorry to be pedantic, but it may have caused confusion, and unless you are fitting very high wattage bulbs which I would not do, it seems like a lot of unnecessary work. IMHO
