How to Fitting new headlamps

Here you can get Fitting new headlamps. Here is Step-by-Step Instructions to Fitting headlamps.

Sealed-beam headlamps are simple to vary, but the way of gaining access to them varies from car to car. To remove a traditional round bezel (outer rim), undo the only self-tapping screw at rock bottom, pull the bottom of the bezel forward and lift it off two lugs at the highest. On some cars you need to remove the front grille, which may be held by self-tapping screws or clips.

Sealed-beam unit and other round headlamps

The sealed unit is clamped into its metal ‘bucket’ by a retaining ring, which may be fixed by three small screws. make sure you do not undo the nearby adjuster screws (See Aligning the headlamps ) by mistake. Remove the ring and pull the sealed unit forward, revealing the three-pin connector on the back.

Pull off the connector to free the unit. On some lamps the retaining ring isn’t screwed on, in which case only the adjuster screws at the top and side are visible. Push the lamp assembly inwards against spring pressure, then turn it anti-clockwise to line up holes with the adjuster screws and free the ring. When you fit the replacement unit, be sure to suit it right way up, which is clear from the lettering on the front. Round headlamps with bulbs are generally attached in the same way as sealed units; but here, when renewing the lens and reflector, remove the bulb, which is held by a retaining clip, not just the connector.

A sidelamp could also be fitted into the rear of the reflector. Turn it anticlockwise and pull it out, along side its rubber seal. On cars with levers for adjusting the beam to allow for heavy loads, confirm you allow the lever within the right position. In any case, set the beam as shown in Aligning the headlamps or have it set at a garage.

Rectangular headlamps

Fixings vary from car to car, but in general they’re simpler than those of round lamps and may be reached from under the bonnet. Typically, the entire assembly is held in situ by one screw – the one which holds the upper adjuster to the front panel. Remove the screw and lever the adjuster away from its bracket with a screwdriver.

Try to not alter the adjuster setting. Pull the lamp forward and up off its bottom lugs. Pull the three-pin connector off the bulb, then remove the rubber sealing cover and therefore the bulb holder (twist both anti-clockwise). remove the sidelamp; it’s a bayonet fitting (twist anti-clockwise) and comes off in one piece with its cover.

Unclip the two adjusters and therefore the lower fitting guide from the old lamp unit and fit them to the new one, then put within the bulbs, refit the connections and lower the unit into place. Engage the lugs at rock bottom with the slots, then push the lamp home and refit the only screw. When fitting a quartz halogen bulb, don’t touch the glass spare your bare hands – this might cause it to fail prematurely in use. On cars with levers for adjusting the beam to allow for heavy loads, confirm you come back the lever to the right position. In any case, set the beam as shown in Aligning the headlamps.

Small lamps

The plastic lenses of small lamps often get broken, particularly on some cars with lamps in exposed positions. Replace a broken lens quickly; otherwise water will get in and soon you’ll need to replace the whole lamp. Corrosion is that the main reason for failure of lamps. On most lamps, lenses are fixed by small screws on the outside, and you replace bulbs from outside too. On others the bulbs are replaced from the rear , for example inside the boot. Here you’ll need to remove the whole lamp to free the lens. Usually this involves undoing several nuts or screws and pulling the lamp free, after which its lens lifts off.

The metal backplate of a lamp with a front-fitted lens usually has studs fitting through holes within the car body, held by nuts or spring clips reached from behind. they’re likely to be corroded, and you’ll got to use penetrating oil. When refitting a lamp of any type confirm that the lamp itself, its mounting point and connections are clean and not corroded. Earthing is typically through the fixing screws, either via the lamp or by a separate earth lead, and if there’s dirt or corrosion anywhere the lamp might not work.
