summary:
HID conversion kits on non-HID ready headlamps (any type of halogen reflector lamps) are bad for you and fellow motorists. it can be summed up in four words: MORE GLARE, LESS LIGHT.
glare causes fellow motorists to be dazzled and blinded by the light and therefore, could lead to nasty accidents. aligning them (pointing them downward) doesn't really reduce the glare but just... points the beam more to the ground - which defeats the purpose of going HID which is to provide better illumination. while these HID kits aren't illegal on our roads, it doesn't mean that we should still keep using them. if we want to use HIDs on our non-HID ready headlamps, retrofitting (installing proper HID projectors) is the way to go. that way, we maximize the use of our HIDs and we don't become a nuisance on the road to fellow motorists.

note on the article (to avoid confusion):
by retrofitting (in the ordinary sense of the word), the author means installing HIDs on non-HID ready headlamps. typical case would be an H4 HID bulb on an H4 reflector headlamp. here are some important quotes to put further stress some important points:
this affirms what was demonstrated in the video linked in the first page: the comparison of a halogen and a xenon bulb on a halogen reflector and the results are clear: the xenon on halogen reflector "retrofit" produces bad output and lots of glare. in the video, they hired a qualified technician and used a beam pattern analyzer to compare. since the comparison was done with the aid of a proper machine, the results are clear and objective: the HID performed worse than the regular halogen bulb. the quotes above point out that subjectively, retrofitted HIDs on reflector headlamps make you think you have better lighting but in reality, you don't. there's also a lengthy (technical) explanation in the article from daniel stern lighting explaining this.The most dangerous part of the attempt to "retrofit" Xenon headlamps is that sometimes you get a deceptive and illusory "improvement" in the performance of the headlamp. The performance of the headlamp is perceived to be "better" because of the much higher level of foreground lighting (on the road immediately in front of the car). However, the beam patterns produced by this kind of "conversion" virtually always give less distance light, and often an alarming lack of light where there's meant to be a relative maximum in light intensity. The result is the illusion that you can see better than you actually can, and that's not safe.
It's tricky to judge headlamp beam performance without a lot of knowledge, a lot of training and a lot of special equipment, because subjective perceptions are very misleading. Having a lot of strong light in the foreground, that is on the road close to the car and out to the sides, is very comforting and reliably produces a strong impression of "good headlights". The problem is that not only is foreground lighting of decidedly secondary importance when travelling much above 30 mph, but having a very strong pool of light close to the car causes your pupils to close down, worsening your distance vision...all the while giving you this false sense of security. This is to say nothing of the massive amounts of glare to other road users and backdazzle to you, the driver, that results from these "retrofits".
the last two paragraphs refer to the popular projector-retrofit modification that's being done nowadays.HID headlamps also require careful weatherproofing and electrical shielding because of the high voltages involved. These unsafe "retrofits" make it physically possible to insert an HID bulb where a halogen bulb belongs, but this practice is illegal and dangerous, regardless of claims by these marketers that their systems are "beam pattern corrected" or the fraudulent use of established brand names to try to trick you into thinking the product is legitimate. In order to work correctly and safely, HID headlamps must be designed from the start as HID headlamps.
The only safe and legitimate HID retrofit is one that replaces the entire headlamp—that is lens, reflector, bulb...the whole system—with optics designed for HID usage. In the aftermarket, it is possible to get clever with the growing number of available products, such as Hella's modular projectors available in HID or halogen, and fabricate your own brackets and bezels, or to modify an original-equipment halogen headlamp housing to contain optical "guts" designed for HID usage (though it should be noted that "cooking" the lens off a composite headlamp, installing HID optics and re-sealing the lens creates major problems of its own, and does not result in a legal headlamp).
ack...
mods please edit the thread title. it should have been "why HIDs on non-HID ready headlamps are bad"
sorry... my bad![]()
This can be moved into the HID FAQ thread instead. Good information there. Hopefully people who've done the retrofitting, will finally see the light...![]()
welcome po sa tsikot lancer-gpx.
Join the campaign.
I'll make a free sig for anyone.

Since there is no law prohibiting the use of such devices, the sale should at least be regulated to those whose cars' headlamps are HID-ready. Indiscriminate use causes accidents and I see a lot of these everywhere.
bad trip nga yung mga yan...
nakakasilaw kahit nasa kabilang part pa sila ng highway.
a cheap, ricey and irresponsible upgrade IMO.
Excessive exposure to the WHAT?
Actually wasn't there a law about using the wrong headlights on cars? Granted, enforcement is always key to any law. I just wish they do it properly this time and get the correct light metering devices. That's a far cry though, knowing how they operate.
hi guys,
thanks for the welcome. i just ran across that video while searching around youtube for hid stuff.
as for local authorities:
maybe they can simplify it: ban HIDs on regular halogen reflector headlamps (H4, H7, H1, etc) and just leave the HID projector-equipped ones alone (retrofit or OE). just an idea ^__^
guys tanong lang po ..
since glaring ang HID sa reflector type Headlight assemblies, pano if walang aftermarket projector HL for the model of our car like in our case na trooper ..
may ginawa lang akong experiment ..
http://tsikot.yehey.com/forums/showt...t=43053&page=4
will these be enough?
and btw, switching to projector type HL ba will save you para di ka ma goon squad?
asking lang po ..
I haven't seen a Trooper or Starex with projectors. so far only from Honda Hatck ek3, ek9, SIR, LXI, etc. Land Cruiser, and D-MAX.
you could go for customized though. I saw 96' surplus Sportages with projector headlights or projector foglamps.
The simple answer will be from the people going towards you.kung naka low sila, tapos nag highbeam bigla kung malapit kana. then you need to adjust it better.
kahit halogen ganito rin. when I replaced my halogen headlamps to a taiwan made clear type. the throw looks ok, but 3/10 yung nag ha-high beam sa akin sa city. tapos kung long distance 5/10. so I realized medyo sabog pala sa malayo yung bili ko. peru mukhang ok sa malapit. so dapat po, you look towards your car and see it in low beam from maybe 10-20 meters. test it with your ride is only the source of light, kung may poste lights etc, kasi, yung mata natin (retina), nag-a-adjust kaya hindi masyado glare sa city. peru sa dark provincial roads grabeh na pala.
saan nga po kaya nkakabili ng projctor h/l na pang starex grx? kase po ung sa akin, bihira ko na lang buksan, kadalasan ung foglamps na lng gnagamit ko, 6000k lng po kse ung gamit ko sa foglamps. medyo sabog nga po ung sa h/l ko kaya nkkasilaw. tnx po.![]()
glad to see more responsible motorists out there.
Again, don't be a victim like me; sayang na pera naka endanger pa tayo ng ibang motorista.
Thumbs up to everyone advocating for these silly upgrades to be outlawed![]()
Hello everyone. Does anyone know kung anong type/model number ng HID ang kakasya sa 07 na CRV?![]()
