s13 S13 Bricks Low Beam Incorrect Pattern

Hello,

I'm struggling to get my low beams to produce the correct beam pattern on Bricks



It's got a beam either side and a hole in the middle

Any ideas?

Bricks are just an old school fixed reflector headlight, and you're in a RHD country so it should 'just work'. What bulb type are you using? As far as I know the outer lens just uses an H4. There shouldn't be any adjustment unless something got warped.

Or are you saying each individual light's beam is OK but they don't meet properly in the middle? Make sure the headlights' mounting tabs aren't cracked and warped, your core support isn't bent, and you're using the OEM inner brackets.

I'm in a RHD country, it's using new H4 bulbs, the individual bulbs are the problem.

You can see its bright either side and dim in the middle

I dunno how crisp an old late '80s lens-optics H4 headlight should look against a tin shed. : )

My first thought then is still that something is focally out of whack, that for some reason the reflector and bulb are slightly out of focus with the lens. It's not adjustable but something could be loose or warped.

Hard to tell what's going on in that image since it's taken during the day.

Hot spots in almost 40 year old reflector housings isn't uncommon.

Bricks have the same light output at night. Get used to it, or retrofit them.

So the problem now is it's not a flat beam all the way across as per the UK mot rules.

Any ideas?

It's not adjustable... you could spend ages pulling the housings apart and trying to focus them.

Your best bet is probably to swap in a set of projectors. Either dual or triple. They produce the correct cutoff for the low/dip beams for the UK.
