Maverick/Terrano HID upgrade

[jims-terrano]

Sorry but no.

If the lamps are properly aimed with good reflectors and lenses (i.e. MOT passable) and the bulb properly moounted in its holder, then no matter what bulb, it can't dazzle.

The problem is, and especially with hi-lo's the HID bulb fitment in its holder is less than optimal in some cases, and the focus point is out, so the beam pattern is not as designed. This is especially true where the hi-lo has a shutter, which isnt in quite the right place.

Don't tell me your one of these people with HID's too?

Terranosaurus can usually come up with regs and laws on bulbs as he's in the trade. I'm pretty sure if an MOT tester will fail them then there must be something wrong with these things.

or seomtheing wrong with the MOT tester :naughty

but i heard fomr a man in the 'new' car trade, that cars fitted with HID as standard need to have some sort of headlight wash and/or wipe system because of the heat generated and things sticking to the lens.

Just take a look at the you tube link & then you will see that you are both right & wrong :thumbs

You can clearly see its a fail but done with a decent bulb or lens & it would be fine :thumbs

Aftermarket hids tend to be in the same league as the boy racers with 100watt dip beams.

The problem with them isnt just poor adjustment its the fact that the intense white beam is more dazzling than a conventional (perfectly adequate for those not scared of the dark) beam when following someone along say an undulating road.

Was there last night over Kirkstone pass

I also understand some better quality hids are linked to car attitude ie suspension or self levelling? this would definitely help, though highly unlikely to be so for most aftermarkets I would suggest.

Definitely lighting for the selfish and the next step on for the headlamp bulb replacement brigade :thumb2

Just thought id check before I jumped in with my understanding of hid ............


effectively the law allows 55 watts for a dip beam and thats it, thats the rule regarding "brightness".

However wattage is the energy used lumens is the brightness produced by the energy.

However on something like your bog standard H4 that gives you up to around 1000 lumens.

On a comparative hid kit 35 watts of energy is used but produces up to or around 3000 lumens.

That keeps them legal with an energy rating of only 35 watts at 12 volts but at least 3 times as bright.

As very few of the cars on the road have their headlights or "point of focus" spot on , its easy to see even without considering inncoent nusiance such as I describe of them following on an indulating road , what a pain in the arse these lights can be and why the lay persons view of them is quite understandably that theres something wrong.

You should always be able to drive and stop within your illuminated , if neccesary, field of vision. If your standard h4s arent good enough either stop at home, drive slower or get a pair of specs

Common Sense rules OK:clap

I can see poeples point as the round Headlights are very poo espsecially when it's wet and the wet dark surfces seems to sap all the light.

good point :thumb2


I may be able to find it and get it posted but I also remember reading a study of drivers and use of lights. It made very interesting reading and came up with some very good sensible points.

It was based on a vehicle with adequate lights so it may be flawed re some cars.

One point was the difference between light and dark areas. If you are concentrating on a very very bright (hid maybe????) illuminated area the difference between that, your periphery vision and darkness where the hazard may be appearing is greater. That means it takes longer for your eyes to adjust and longer for you to react if you are , as youre supposed to be, looking all around.

ie the brighter your headlight in the illuminated (dont confuse with range of vision) area the less youll actually be aware of around you.............

I agree with that, imagine sitting by a camp fire it makes the darkness beyond seem darker! That's why i prefer to go for evening walks without a torch as they just ruin your night vision.
