Hilux N70 Factory-Style Headlight Install Guide

A factory-style replacement for the Hilux N70: the grille comes off, the old headlights unbolt, your globes move across and the new ones bolt to the same mounts. Allow about an hour, plus time to aim them.

Before you start. Engine off, key out, lights off. Disconnect the negative battery terminal (and any second battery).

Do one side at a time, so the other side shows you how it all goes back.

Tools

10 mm socket, extension and ratchet
Flat screwdriver and a plastic trim tool
Masking tape, marker and tape measure

Install

1

Mark the beam height

1
Park on flat ground with the headlights 5 m from a flat wall (measure from the lens). Measure from the ground to the centre of each headlight and put a strip of tape on the wall at that height, in line with each light. You'll aim the new lights to these marks.
2

Remove the grille and factory headlights

1
Open the bonnet. Undo the clips (and any screws) along the top edge of the grille, then pull the top forward and lift the grille out of its lower tabs. The clips get brittle, so go gently.
2
Undo the 10 mm bolts holding the headlight. The top and inner ones are easy to reach once the grille is out.
3
The lower outer mount sits behind the bumper corner. Undo the screws holding the bumper corner in the wheel arch and ease the corner out a little to reach it.
4
Ease the headlight forward and unplug everything behind it: the H4 headlight plug (press the tab), the park light socket and the indicator socket (twist each a quarter turn).
5
Keep these: twist the H4 headlight globe, the park light globe and the indicator globe out of the old headlight. They go into the new one.
6
Keep these: twist the park light globe and the indicator globe out of the old headlight. They go into the new one. The old H4 globe can go in the glovebox as a spare.

Prepare the new headlight

1
Check the new headlights match your old ones (2005 – June 2011, or the July 2011 – 2015 facelift); the two aren't interchangeable.
2
Seal the lens joint: run a thin, even bead of the supplied sealant along the joint between the housing and the lens, all the way round with no gaps. It keeps condensation out. Do it before the headlight goes in, and let it cure before washing the vehicle.
4

Fit the globes and connect

1
Fit your H4 globe into the new headlight. Don't touch the glass; skin oil makes it fail early.
2
Fit the H4 LED bulb into the new headlight. Twist it in until it locks and keep any driver box or cable tied clear of hot parts. Don't touch the LED chips.
3
Refit the dust cap firmly over the back of the globe.
4
Fit the park light and indicator globes, then plug in the H4 plug, park light socket and indicator socket. Push and twist each until it locks.
5

Test, then bolt in

1
Reconnect the battery. Check low beam, high beam, park lights, both indicators and the hazards. The indicators should flash at the normal speed.
2
Battery off again. Bolt the headlight in with its factory bolts. Cable tie any loose wiring away from the radiator, fan and anything hot or moving.
3
Do the other side the same way, then refit everything you removed in reverse order and reconnect the battery.
6

Aim the headlights

WALL5 mTape mark:headlight centreCut-off 7.5–10 cmbelow the mark
1
Park in the same spot you marked the wall from. Tyres at normal pressure, nothing heavy in the tray or back.
2
Low beams on. Hold a piece of cardboard in front of one headlight while you aim the other.
3
Set the top edge of the low beam (the cut-off) 7.5 to 10 cm below your tape mark, pointing straight ahead. Use the adjuster screws on the back or top of the headlight.
4
Check both at night on a quiet road. Oncoming drivers shouldn't flash you.

Troubleshooting

One headlight doesn't work

Check every plug is fully clicked in at the headlight, and the harness is pushed fully home.

Indicator doesn't work

Check the indicator globe is seated and its socket is twisted fully in.

LED bulb flickers

Reseat the H4 plug on the LED bulb and check the bulb is locked in. Still flickering: message us.

Light fogs up inside

A little condensation after a cold night is normal and clears once the lights have run. Check the dust caps are on firmly. If it doesn't clear, message us.

Beam looks too high or too low

Re-aim it with the vehicle level and unloaded.

Rules for aftermarket headlights vary by state. Check yours before fitting to a registered vehicle.
