@Sandykudva I really appreciate your reply. the way you just replied.I just love it. I am very thankful to you that you gave your precious time to solve my queries. You helped me so much by your answers that now I will take these things in consideration before buying any set of headlights for my car. Thanks a lot
that means a lot to me.
But after this discussion I'm surprised
to know that xenon don't even perform well in projectors. earlier I thought that they they don't work well with reflectors but than I wonder how the cars with a single projector and xenon like Audi A4 work so well. the basic format for the headlight, companies use with xenon lights is they use xenon for only low beam in projector and the high beam is standard halogen in the reflectors and the xenons are always in the range from 4500k to 6000k (we have toyota fortuner and many more with this type of setup in india) and most important part when some car approaches is that in low beam you should have a good visibility, xenon works best to help you get low beam from the oncoming traffic but it doesn't help you even when the arriving car is in low beam. this is the what stoping me for going with a single projector even the official vw headlight is the foreign version of polo with projector and LEDs uses a projector with xenon in low and halogen in high. after this discussion I wonder that will only xenons in low beam help. :(
So after trying xenons earlier in my bolero I didn't go with those in my polo. I wanted projectors to use them till that time I purchased Philips Diamond Vision 5000K 55/60W white light bulbs as this didn't required any relays etc. as I didn't want any electrical etc work in my car outside vw as I had a very bad experience with my bolero's wiring with aftermarket work but these halogen white bulbs too disappointed me. these too behave like xenons only difference is that they don't force the oncoming traffic to give me an instant low beam. otherwise they behave same as xenons they don't provide the visibility when nearing a oncoming vehicle. :(
I think the problem is the white colour of light as the yellowish colour of halogen gives a very good visibility in most cars for eg I can say indigo cs , safari storme , xuv 5OO etc etc but not The Polo.
After searching I got one more type of light and they are very new to the market so the major manufactures for now don't have that product and that is LED headlamps. they come in white light ranging btw
4000 to 6000K but they don't give glare to other drivers like the xenon and I think in India the more the glare in high beam the more rapidly you get a low beam from others but the low beam is also important. so I am thing to also try and experiment with LED headlights but they are also for now very expensive. :'(
What I planned for polo is a dual beam headlight like the new polo has and customize it or find a pair on net. that can have following forms.
1. Both projectors one xenon and one LED/Halogen both having high and low beams.
2. One projector and one reflector , projector with xenon and reflector with LED/Halogen.
3. Simply have new polo's headlight and go for LED/Halogen for low beam and xenon/LED for high and both are reflector and each have different function one only has low and one only has high but in high beam both reflectors are on and in low only one of them is on
And each having LED tubes either way inside or outside the headlight unit.
And at this point from the 3rd form one que arises in mind that the reflectors have different functions one with only low and one with only high so if I fit a low/bulb any of xenon/halogen/LED will that work for both high/low or or if fit projectors by customising them will the projectors work in both hi-low beam or not. so just researching on this que and if I get a positive ans for this I will definitely go for the 3rd one.
So finally comming to an END one last point I would like to share that as you told me that your headlights gets some fog/water vapours and goes off when lights on. I have same problem with my right fog lamp. I got that opened at VW and found no crack etc to enter water and thought it could be some other reason than a few days back got my eyes attracted towards my fog lamp and what I find is a little amount of water in it. that was the reason of fogging up of the lamp and I was like yaar obviously how will water vapour come without water inside. OMG
So I think you should also check if there is some water inside your headlight which fogs up. :)
Now adding some pics for reference for the above discussion. I am using my mobile to operate this so was unable to input pics at the same time where I m talking about them. hope I get some editing option after uploading them to arrange.
And hope this thread help everyone who reads it discover some new ideas and solutions for there headlight related problems. :D
THANK YOU ONCE AGAIN
