Marchal 653 Driving Lights

[RichardH]

Looking to adjust my Marchal driving lights, as the OS one seems to be more of an aircraft landing light than a driving light.
These are both bolted straight on to the lower light box in the nose clip by 2 bolts.

How have you guys adjusted yours?

 

I fashioned an aluminium spacer that ran from bolt to bolt and across the top of the light (between the lens and the inside of the light box). Only needed a half a millimetre thickness to give enough tilt up, and worked well. Same would apply across the bottom if tilt down needed. Just make thickness to suit.

Are your lights mounted from the front, or from the rear?
It appears that mine were mounted from the rear, which doesn’t have a flat surface.
I have just tried a few things out and need to pack the bottom out by 8mm!
I would like to fit some form of adjustment, rather than a fixed plate (plus an 8mm plate is rather a lot).
I will have to give it some thought

 

Mine are mounted from the rear (i.e. inside the light box). Yes - 8 mm is a lot.

This may annoy the “originality is everything” officionados in here, but here is my attempt at something similar. I have got to try final fit and adjust, but preliminary trials show they should work.... and all from off the shelf items, with a bit of fettling

More pics when fitted.

In situ, and easy adjustment .

Light unit is mounted on long screws with locknuts under light, and small grommets fitted over to allow movement but still locate accurately.
