headlight

A headlamp is a lamp attached to the front of a vehicle to illuminate the road ahead. Headlamps are also often called headlights, but in the most precise usage, headlamp is the term for the device itself and headlight is the term for the beam of light produced and distributed by the device.
Headlamp performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities: the US National Highway Traffic Safety Administration states that nearly half of all traffic-related fatalities occur in the dark, despite only 25% of traffic travelling during darkness.Other vehicles, such as trains and aircraft, are required to have headlamps. Bicycle headlamps are often used on bicycles, and are required in some jurisdictions. They can be powered by a battery or a small generator like a bottle or hub dynamo.

    Replacement Headlights

    Hi all, Im sure this has been asked a million times. Am I correct in thinking the original bulbs are HB3 9005. I have just bought HB 3 9006 and they dont fit. It seems as you twist the bulb in place the black plastic lugs are different sizes? They are smaller on the new bulbs. Can anyone help?

    Standart vs Luxury Headlights

    Just wanted to ask how big the difference in quality really is. The standard headlights seem to have a projector, while the luxury ones use parabolic reflectors. Usually, projector headlights are considered better and also more expensive to build — therefore, I’m a bit confused and would like to...

    MGS5 headlights.

    My opinion is that my MGS5 probably dazzles oncoming drivers unless the road is dead straight and level. So I've decided to try lowering them to number 1 and I'll see how this works out. Based on a normal 2 person front seat occupancy and no real load in the boot. Moving on with no front fog...

    Random headlight failure

    Hi, thinking this might be useful for other members. This morning all the front lights failed, "started" the car and not only did the headlights fail to come on in the dark, but the side lights and running lights were all off too.

    Auto dip headlight - how to reactivate?

    Usually I don’t touch the auto dipping headlight function - it just works automatically. Tonight, coming home, it seemed to have deactivated itself. I could not reactivate it. Is there a knack or secret switch?

    Left hand drive headlight

    Anyone know if the left hand drive headlight is adaptable for right hand drive? I was sent the wrong one and the cut off line is in the middle instead of on the left where it should be. I moved all adjustments on headlight, only one I didn't see what it does is the one with the rod at the back.

    Uneven Headlights

    My drivers side headlight appears to be blocked at the top of the beam, creating a sharp dark cut off on the road ahead, while the passenger side beams way ahead of the driver's side. MG service says it's normal for the Drivers side to be lower, but this feel quite restricting in how far I can...

    No headlights

    Hi all. Driving home this morning I lost my headlights ( side lights working) Both went off at the same time. Think it could be a fuse that's gone. I've managed to get the side panel off but look like it's not that easy to get to the fuse box. Any tips or idea's Thanks Mick
