Height of Headlamps
The Doc - 1/8/07 at 10:24 AM

My headlights are mounted on a bar clamped down onto the chassis (as per book)

This sets them just within the 500 mm height minimum and and down quite low between the nose and wings. Is there any issue with beam related to this?

Only problem of having the lights low is they're slightly more likely to clash with the wheel arch on full lock.

For SVA if you've got adjustable shocks you could always wind some pre-load into the shocks to raise the ride height (and therefore the headlights). If you have to over-inflate the tyres to get self-centering this will also raise the ride height a little...

Also (if you've got any slightly borderline lights) after you turn up for the test (but before the measuring begins) you can give the front and back of the car a gentle lift. You'll usually find the springs will keep the car a bit higher until the next time you go over a bump or compress the shocks.... Of course canny SVA testers will check the shocks by bump-testing the car corners before doing the light test to get rid of this advantage....

IT does work though- my ride height runs @ 75mm most of the time but if I lift the front and back of the car it'll settle quite happily @ 90mm until the next time it's compressed.... Useful for getting over jacks, getting oil drain trays under the sump etc....
