I have no problems with HID headlamps on modern cars as long as they're aligned properly. By this, the car should be in D (if automatic) and slightly loaded with maybe one or two people, to simulate the upward projection of light when the rear suspension is compressed. That way kahit puno yung sasakyan, it will not blind oncoming traffic because it is aimed lower.
The problem with high beam users is they compensate for the lack of lighting by providing enough light for themselves but neglect other drivers. HID's when properly aligned should light up a broad band of forward facing light with a sharp cutoff usually even on both sides, compared to the more traditional halogen bulbs that have a __/ __/ cutoff.
Also note that the roads are never smooth in Manila, so when somebody is approaching you, and his part of the road is ever so slightly uphill, try not to impulsively flash your lights as if to say "nakakasilaw" for all we know the road is not even and he's just passing by harmlessly.
Making HID's modular to use in the provinces and swappable for halogens is way too impractical for any car manufacturer to even think of doing. There is no point in doing so unless you have so much time and space in your trunk for an extra pair of headlamps but with halogen bulbs instead, already properly aimed and ready to plug and play.
I couldn't agree more.
People who buy cars that have HIDs standard are not kulang sa pansin, they just want fresh, new technology that can provide safer driving both for them and their passengers. However, proper use is tantamount to responsible ownership. I don't know if it's standard protocol for dealers to properly align the HID headlamps. If it's not, then it should be. Owners should also be informed of the potential danger they pose to other motorists if their lamps are not properly aligned. Also consider some of these cars may have been in frontal accidents where the headlamps might not be aligned due to the impact. However, people who retrofit HID kits to their vehicles must do so properly and this entails the use of correct equipment and proper alignment thereafter.
I'm sorry but calling owners of HID-equipped cars as "kulang sa pansin" is ignorance. In fact, the use of HID's in the metro is advisable because it provides a very broad band of forward light that can illuminate the immediate foreground, the sides, as well as a good distance far away forward. The sharp cutoff above the point of illumination prevents motorists as well as pedestrians from receiving upward glare. There is a reason HID's are becoming standard on most high end cars, just as there was a reason why halogen lamps were used to replace sealed beams two decades ago. Sadly, when retrofitting to upgrade their lighting, some owners do not retrofit their cars properly and have limited knowledge of this. More so, when upgrading SUV's or higher vehicles, it should be aimed much lower than standard sedans. This is to avoid glare that goes straight onto the windows and mirrors of sedans.
As you can see, aiming is key because one, the light illuminates the important parts of the road, and two, it prevents untoward glare to other motorists. If you install HIDs on the car as in a retrofit, but do not aim them properly, then you should be ticketed for improper use of HIDs. The same goes with improperly installed HID kits as with the use of the wrong reflectors, components, etc that just scatter light and cause even more glare. Like I said earlier, ownership responsibility is another key.
Then again, sadly, that's not how everything goes.Last edited by mbeige; November 15th, 2007 at 03:28 PM.
