New carlightblog series: Fogging inside the headlamps and what you can do about it
The topic is a major one among our readers and in the various forums: Moisture inside the headlamps, usually evidenced by fogging on the inside of the lens. Headlamp engineers say they can never prevent it entirely, but we’ll tell you what you can do.
Fogged up headlamps, Part 3: The severe cases
Modern headlamps have a very practical ventilation system that largely should prevent fogging. And it does for a long time, until suddenly the headlamps start fogging up more and more. What can you do then? Maybe one of the vents is clogged. The top ones usually are easy to reach, so you can inspect and clean them if necessary. In some car makes there is a piece of foam inside the vents, which you can also clean. Quite often insects find their way into these openings as well. The bottom air inlets make cleaning difficult. Cotton swabs do a good job if you can reach them without dismantling the headlamp.
Cleaning the vents on the headlamps can do wonders for preventing fogging.
Evaluating light like the pros – the Car Lighting Selector
One of the many questions car-buyers ask is about light. Is the extra money worth it for xenon light? Is LED light any good? And what about alternative beam patterns or bend lighting? The Car Lighting Selector from the LightSightSafety initiative helps to find the right answers.
EU Commission confirms LED headlights as fuel-saving technology
It is now official: light-emitting diodes in headlights contribute to lower fuel consumption and as a result to lower CO2 emissions. According to Audi, it has already received a corresponding certificate.
Test rig experiments identified a decline in emissions as a result of LED headlights in an A6. Dipped beam, full beam and licence plate lighting were switched on during the experiments. The ten cycles of the New European Driving Cycle (NEDC) revealed a CO2 decline of more than one gram per kilometre. (more…)
The Cockpit offers numerous possibilities for creative ambient lightning
Nothing in a car is as boring as a single, dim interior light. But you can do something about it: Unlike the exterior lighting, the inside of a car is a free zone when it comes to improving the light. The first step you can take is to replace incandescent lamps with light-emitting diodes (LED).
Retrofits with LED technology bring interior lighting up to the latest technical standard.
