LED & HID bulbs and the new MoT regs
- Thread starter BOBAD
- Start date
Unit has arrived from China, they are surface mount chips.
The first problem on fitting is that the 14mm diameter hole underneath for the locating spigot grommet is actually a 14 x 20 mm slot this allows the unit to pivot on the side mounting rubber bushes by 6mm.
This gives adjustment from too high to way too low and no way of locking it in position.
Perhaps there were parts missing?
Rather than bodging it into place I decided it best to make an adjuster from stainless.
I turned a top hat washer to fit in the slot and give a 3mm bearing face on the grommet, fabricated the rest, welded the washer to the assembly and riveted it to the case.
My other concern is that the plastic lens seems very thin ( if polypropylene this would be fine but I suspect it is cast acrylic or similar).
The front cover does have four holes which are a good fit for M5 rubber expanding bushes so I will make a guard / cover from clear acrylic sheet and black Nylon 66 spacers.
Perhaps I should have ordered the cover offered.
I would be interested to know if others had an adjuster included with the unit especially those that are for sale without the bottom locator.
Will try to post photos later.

I just fitted a rubber grommet to the hole in the base. It doesn't seem to move too much when it's fitted on mine. Tbh I used to get an aweful amount of headlight and Speedo shake with the standard unit, especially when I had TKC80's fitted. Can't see it being ant worse. I fitted the BMW headlight guard that I had on my standard light unit to mine. You can see it in the photos I previously posted. Using this it's easy to just pull the cover off to clean behind it if needed.
That's a nice job in the adjuster though. I'll see what mines like when I get out on it.
I did the same as Gazza with the Rubber Grommet Chris.
Nice job[/url][/IMG]

. Maybe a bigger thumb wheel on that end nut so you don't need told?The 'radical' designed unit doesn't accommodate that spigot on the sub frame. Been wondering about and adjuster, but I seem to have fixed it in about right.
But that looks good!

I've got practically no shake on mine. Wondering if you used the threaded screw mounts that come with the unit? I mean rather than just reusing the rubber grommets from the OEM unit?

I said the replacement headlight seems to fit more solidly than my standard one. It didn't come with any threaded nuts I just used the standard rubber grommet with captive nuts from the OE headlight. Seems fine to me.
I used a 1/4 drive knurled thumbwheel with hex bit to adjust and a small 8mm ring spanner fits over the allen head to lock it off.
I agree if I thought a regular adjustment was necessary I would have used a knurled thumb wheel and spring.
This was just the next option up from cutting another grommet in half and wedging it in place.
The dip beam cut off on these units is really good a very sharp line and no scatter.

There were no fixings included with the headlight so I used the OE mounting rubbers.
As there is no bottom hole on your unit the solid mounts supplied explains your lack of movement.
Ah! Apologies. Obviously misread
Glad it's all good.

Good point. That may well be the reason they supply them.
Mine is not of a mixed bag in the end as I couldn't believe there was no damping. So I have actually bastardised their fixing and included a thick rubber washer. Not entirely sure if it helps as it's all locked up pretty tightly. But so far so good

My GSA TC flew through its mot last Saturday with a HID main beam and LED high beam fitted, I have just come across this thread and am now £143 lighter and waiting for a parcel to arrive in the next 7-15 days 
You won't regret changing - when it arrives. Trust meMy GSA TC flew through its mot last Saturday with a HID main beam and LED high beam fitted, I have just come across this thread and am now £143 lighter and waiting for a parcel to arrive in the next 7-15 days

Went to fit mine today and this is also my issue
It cant be 'locked' in postion like the OEM as the grommet slides forward or backward through the slot rather than on the OEM where it is being fixed in postion on the peg
Not so cheap chinese tat !
It would be nice if someone could 3D print some adjusters as it turns the slot into a bonus and makes adjusting easy.
Feel free to use my method or improve on it.

Tbh mine with a large grommet in The slot doesn't seem to move when the side bolts are tightened up. Had a ride out yesterday and the clocks and headlight seem to be less prone to vibrating than with my stock headlight.
Would be nice if someone could 3D print an adjuster, I'd certainly be a customer.
I copied your idea (not as well fabricated as yours) it does the job though and it's quite a difference in throw from lowest to highest position.
Not been out for a night ride since fitting it but certainly won't be any worse than my original ride with the new light set way too low

This is also my experience of the new Unit.
Are the Problematic ones the newer (more radical) shaped ones?
Mine is a copy of the OEM 2007 Version and seems Ok.
I'd be more than happy to print an adjuster mechanism.
I'm not however entirely clear on dims, spaces, etc. My headlamp has no slot, nothing underneath. A sketch will do. Maybe pics too. I can work some of it out of course.
