Adjust headlight beams 1994 SC

Hi all


Does anyone know how to adjust headlights beam level, have taken the left front headlight out, what would be the correct procedure to aline headlight beams.

In the pic Id already removed the left hand headlight



The right hand headlight is low indicated by the "L" Low

The left hand beam Ive marked the leave as "H" High

"M" is the midpoint between L and H

Thanks for the input

Good evening,

The adjustment screws are inside the van on the firewall down low, not the outside like you’d think. I’ll take some photos in the morning for you.

^ Yes ours when we had it had some rubber covers which you remove to access the adjusters. Make sure you refit them and that they seal well or you'll get water coming in (yes we did and wondered where it was coming from as we never needed to adjust the lights).

Hello and welcome!

There are a few post on this forum about headlight adjustment and some include pictures of the mechanisms (see: https://hiace-super-custom.forumotion.com/t74-headlight-adjustment?highlight=headlight, for example). Searching the forum is a good place to start as your question might already have an answer or a partial one at least.

Be very careful when trying the adjustment controls as they are quite fragile and won't work if the mechanisms inside the headlight unit are crusty. If you need to adjust the beams and think they haven't been touched for ages my advice would be to pull the light units out and work to sort out the linkage inside the units first. If you hear a clicking sound then it's likely that the splined adjustment pin is turning is a cracked cog (ask me how I know).

Replacement adjuster units are available and not hugely expensive (see the various online Toyota parts catalogues that people use) but preventative maintenance might save the day. Some people have suggested removing the adjuster mechanisms but then you'll have to drill new openings in the bulkhead so you can access the turning stubs directly (and will need a suitable tool). If you drill new openings you'll ideally paint the bare metal and fashion a new plug and you'll probably have to remove the headlights to work out where to drill.

Adjusting these headlight (and the fogs have an adjuster, too) is all a bit of a faff but better to have the mechanism sorted before inspection day as I'd expect inability to get the correct beam pattern will mean a failure. Thoughts?

Cheers.
