As far as I am concerned I am studying other option of Hella Aux. Lamps due to Figo reflector Design. One of Fellow BHPian has installed such lamps and I am in touch with him before I conclude on this issue. |
Rightly said, 4.3K is more close to day light as per the expert opinions. Anything more than 5K is just for show off as it will not give optimum visibility in all weather conditions.
The best option will be the aux lamps, you can check Hella FF series for short range with wide spread AFAIK and Comet series are known for long range visibility, with just 55W it will give you the best pencil beam which is good for high way cruising. FF series are more economical than Comet series. Quote:

Thats a common issue for new gen entry level hatches AFAIK. I have a Beat which gracefully scrapes almost every dips on the road if I don't take care of it properly. Quote:

Sajit your comments on this are very Valuable since you have experience with Figo lighting. |
I would say you can check out the Hella aux lamps any day as the first option. Even with the standard 55W halogen proves to be the best bet unless you are a light maniac who wants to teach a lesson to all high beam riding morons, if so go for HIDs on aux lamps. But I would say you are going to give 2X or even more glares than you plonk the HIDs on the stock reflector but with a slight difference, you will be armed with a search light with HID backup. Its really dangerous on roads, but the fact is there are many "morons" are already on the roads with HIDs on aux lamps which has no beam cut offs to prevent glares to even to a min level. Its your call to be a responsible person to you and others as well. Quote:

Even on aux lamps, HIDs will cause glares as its not designed to handle the intensity of the HID and many parameters have changed like light source, incompatible optics etc.
Am no expert in this and I know optics is a very complex thing to understand. But, I came across some interesting findings when I did some experiments with HIDs on reflectors:
1. The round shaped reflectors are producing less stray glares than the other shaped ones as its got better focus.
2. On any reflector, putting HID the focus is altered due to mainly light source, secondly the bulb seating positions. ie; the glowing portion of the bulb is different in a halogen and HID.When I took a wall projection of a HID on reflector (round) it was giving glares to sides due to the MFR design mostly, then I tried to pull the HID capsule towards back without locking it to the reflector socket to see any focus change, it was giving better spread as well as less glares. Sadly, at that point we can't fix the bulb to the reflector as its too way back from the lock. Unfortunately I don't've any pics to share with you. So this reveals there will be serious focus issues due to the HID conversion kits on normal reflectors.

Hope this will give some insights to you when upgrading lights.
