LandCruiser 100/105 Series LED Projector Headlight Install Guide
Fits the LandCruiser 100 and 105 Series, 1998–2007. The grille comes off, the old headlights unbolt, and the new ones bolt to the same mounts and plug into the factory sockets: high beam, low beam, park light (that runs the DRL) and indicator. Nothing to splice. Allow 60–90 minutes, plus time to aim them. Built before the June 2005 facelift? You’ll also need the facelift under-headlight trim (Toyota part) so the headlights line up and sit flush.
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
Phillips screwdriver
10 mm open-ended spanner
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 fasteners along the top of the grille and ease it out. The clips are brittle with age, so go gently; spare clips are cheap.
2
If the corner indicator lamp is in the way, it comes out first: undo its Phillips screw from the top, press the lamp body inward while you slide it forward, then unplug it.
3
Bumper cover corner: remove the 3 trim clips and the corner bolt, then ease the cover down a little to reach the lower outer headlight bolt.
4
Undo the headlight bolts (usually 3 per side; some have a 4th underneath). The lower outer one is tight: a 10 mm open-ended spanner helps.
5
Ease the headlight forward and unplug the high and low beam plugs (press the tab), the park-light socket (twist a quarter turn) and the indicator.
3
Connect the new headlight
1
Plug the factory high beam (HB3) and low beam (HB4) plugs into the new headlight. They look alike but are keyed differently, so each only fits its own socket. If one won’t go in, swap them over. Push in until they click.
2
Tape up any factory plug or socket that has nowhere to go, so it stays dry, and cable tie it clear.
3
DRL and indicator: plug the factory park-light socket into the new headlight (twist it in a quarter turn). The DRL comes on with your parkers. Then plug in the indicator.
4
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
Check the DRL comes on with the park lights.
3
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.
4
Do the other side the same way. Refit the bumper cover clips and corner bolt, the corner indicator lamp and the grille, then reconnect the battery.
5
Aim the headlights
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. The adjuster screws are reached from the engine bay.
4
Check both at night on a quiet road. Oncoming drivers shouldn't flash you.
Troubleshooting
One headlight doesn't work
Check the high beam, low beam, park-light and indicator plugs are all clicked fully home at that headlight.
A plug won't go in
The high beam (HB3) and low beam (HB4) plugs are keyed differently. Swap them over.
DRL doesn't come on
Check the park-light socket is twisted fully home and the park lights themselves work.
Dash warning light
The 100 Series doesn't usually show one. If you get a warning, message us with a photo of the dash.
Light fogs up inside
A little condensation after a cold night is normal and clears once the lights have run. If it doesn't clear, or there's water inside, message us.
Beam looks too high or too low
Re-aim it with the vehicle level and unloaded.
Built before June 2005? Fit the facelift under-headlight trim (Toyota part, sold separately) so the headlights line up and sit flush. Rules for aftermarket headlights vary by state. Check yours before fitting to a registered vehicle.
