I have a Nissan Terrano which I intend to travel to Rome with. The clear glass headlamps make it difficult to know where to place the legally required beam benders. Does anyone have any ideas as to the correct positioning of them?
Thanks, I'll have a go!!Hi Philip,
I had the same prob with my C5. Clear glass and the dealer wanted something ridiculous to put a shatterproof cover over the lights that shows where to put the beam deflectors.
All you have to remember is that from the drivers position the right or offside of the headlight sends beams to the left and the bottom of the headlight sends beams the furthest. These are the part of a British cars headlights that dazzle on the continent.
So all you have to do is cover that part of the headlamp that is likeliest to dazzle. Get down on your knees and with a felt tip pen mark the exact spot on the glass that coincides with the position of the bulb. Now draw a line horizontily from that point to the offside of the headlamp. Now draw a line vertically from that first spot you did down about 2cms. From there, draw another line again towards the offside but at an angle of 15 degrees down from horizontal.
I hope this is making sense. Now, fill in the area you have marked with black insulating tape trimming neatly. Wait 'til it gets dark and try it out on the garage door. There will be a slight reduction in the amount of light from the headlights but not so you would notice. In addition the gendarmerie will note that you have prevented any of the natives from being dazzled and leave you alone. Hope this helps and have a good trip.
Dear LutzYour suggestion makes sense but it only really applies to cars with regular headlamps. As soon as you have self adjusting xenon ones, especially when main beam and dipped beam are separate light sources inside the same headlamp unit, there's no bulb to align against and it's going to be difficult to mark the field which you want to blackout. And the method doesn't work at all if you've got one of those new high-tech cars with adaptive forward lighting because the light source moves to the left and right as you steer. In such cases you really have to go to the dealer to get him to readjust the headlamps.
It still going to be a problem, though, if main and dipped beam are separate but behind the same lens. The main beam bulb is usually located inboard of the dipped beam so if you apply the method that you suggest, one would probably blank out most of the main beam on the right hand side of the vehicle.Your suggestion makes sense but it only really applies to cars with regular headlamps.
