How do you adjust the dip beam headlights on a Vauxhall Astra?

The dipped headlights on my 56 reg Astra have always been poor, but the service agent says this is the standard factory setting. When switching to dipped beams the lights point left so I can't see the white line in the centre of the road. The dip lights need adjusting to point straight ahead rather than to one side. As the garage won't do it, how do I make the adjustment myself?|||You remove the headlight covers and then proceed to replace each johnson rod coupling.|||A “Johnson Rod” is Seinfeld (show) slang for a fake mechanical part used to jack up the price for ignorant people. There is no such thing as this part. And the best-answer is simply more point-gaming by Jehovah-boy. So obvious, and yet he keeps denying it.

By the sounds of it they need setting up as they are way out of alignment and borderline dangerous. Take it to another garage and get them set up properly or check your manual as it will say in there where the adjusters are for each headlight unit. Then park facing a wall so you can see the beam pattern and adjust as necessary. Do not go too high though as you will blind oncoming traffic andmay cause an accident also if adjusted wrong it will fail the MOT.|||They are supposed to point down and to the left - if they do not they will dazzle and fail an MOT. The lenses are designed to cut the lights distance to the right and pick it up higher and farther to the left. When there are no oncoming cars you use high beam which will light up the lines.


When there are oncoming cars you need to not look at the lines as they are too near thepoint where the oncoming headlights are and they will dazzle you. Keep the onoming traffic in yor peripheral vision and look a little to the left.





To increase night vision -


Fit higher output headlight bulbs


If adjustable lower the interior panel dash light level to as low as possible whilst still being able to see the dials.


Get your eyes tested - low light and night vision is the first thing to go.
